ASTM D Certification

This specification covers plastics and products made from plastics that are designed to be composted in municipal and industrial aerobic composting facilities. The properties in this specification are those required to determine if plastics and products made from plastics will compost satisfactorily, including biodegrading at a rate comparable to known compostable materials. The purpose of this specification is to establish standards for identifying products and materials that will compost satisfactorily in commercial and municipal composting facilities.

ASTM D Certification

This specification establishes the requirements for labeling of materials and products (including packaging), wherein a biodegradable plastic film or coating is attached (either through lamination or extrusion directly onto the paper) to compostable substrates and the entire product or package is designed to be composted in municipal and industrial aerobic composting facilities. This specification, however, does not describe the contents of the product or their performance with regards to compostability or biodegradability. In order to compost satisfactorily, the product must demonstrate each of the three characteristics as follows: (1) proper disintegration during composting; (2) adequate level of inherent biodegradation; and (3) no adverse impacts on the ability of composts to support plant growth.

Bagasse

A biodegradable and compostable material that is made from sugarcane fiber leftover after juice extraction. This fiber is made into disposable products normally made from plastic or virgin paper.

Bags on a Roll

Continuous roll of seamless tubing perforated under bottom seal. Bags must be torn off to open. View Flat Poly Bags on a Roll. View Gusseted Poly Bags on a roll.

Bag Signs

A bag sign is a plastic bag that is stretched over a wire frame. Typically, the wire frame is rectangular with an open end. The two wire rods on the open end are pressed into the ground and the bag sign is stretched over the wire frame to display the printing on either side of the bag. The bag signs made by Custom Poly are printed on LDPE film with a special backing to prevent sunlight conditions from interfering with the printed message on either side of the sign. Bag signs are most familiar during election years when candidates use them as part of their campaign efforts.

Barrier Film

Specially formulated film typically used to extend the shelf life of food products. Prevents transmission of moisture and gases.

Biodegradable

A material that is capable of undergoing decomposition into simple compounds such as carbon dioxide, methane, water, inorganic compounds and biomass. The predominant mechanism for decomposition is the enzymatic action of micro-organisms. There are no requirements regarding residues or time to breakdown.

BPI (Biodegradable Products Institute)

The U.S. standard in compostability. The BPI Logo Program is designed to certify and identify plastic products that will biodegrade and compost satisfactorily in actively managed compost facilities. The BPI and US Composting Council (USCC) use American Society for Testing and Materials Specifications (ASTM) to approve products for their “Compostable Logo” effort. These specifications are the result of 8 years of intensive work by researchers, product manufacturers, composters, and resin producers to identify plastic and paper products, which disintegrate and biodegrade completely and safely when composted in a municipal or commercial facility, like kraft paper, yard trimmings and food scraps. In order to be BPI certified, products must meet ASTM D or D standards based on testing in approved independent laboratories.

Bioplastics

Bioplastics, also called organic plastics, are a form of plastics derived from renewable biomass (living and recently dead biological material) sources, such as vegetable oil, cornstarch, or pea starch, rather than fossil fuel plastics which are derived from petroleum.

Black Conductive Film

An anti-static film made with a carbon black additive. A humidity-independent, corrosion-resistant, non-contaminating film with a long shelf life. View Black Conductive Poly bags.

Bleached White Kraft

Common paper bag. Bleaching is done by a chemical process.

Blown Film

The most common method of producing film and bags. Resin is melted in the extrusion process and blown vertically into a bubble to cool.

Bottom Gusset

A bottom gusset is formed by pushing the bottom, closed end of a flat poly bag up, into the bag interior making an accordion type fold or pleat at only the bottom of the bag. Bottom gusset bags are always sidewelded. The size of the bottom gusset is measured across the open or unfolded dimension. The bottoms of plastic bags constructed in this manner sit more or less flat on a surface when filled.

Bottom Seal Bags

Individually cut bags from seamless tubing, sealed on the bottom. Flat or side gusseted bags with a seal – usually have a tail.

Back to top

"C" Cut Handle

A carrying handle die-cut into the top of the bag that leaves a flap of material in place

Cast Film

Extruded in sheet form through a slotted die.

CFC's

CFC's, or Chlorofluorocarbons, are a mixed group of chemical compounds composed of carbon, fluorine, chlorine and hydrogen alkenes. They are nontoxic and nonflammable and can be readily converted from a liquid to a gas and vice versa. Their commercial and industrial value notwithstanding, CFCs have been found to pose a threat to the environment through ozone depletion.

Clarity

Transparency of the film based upon surface gloss and haze.

Coated

Clay or other material coating on paper to make it smoother and less absorbent to ink. Produces a smooth finish and better print, but can rub off and crack on folds taking the ink with it.

Compostable

Capable of undergoing biological decomposition in a compost site as part of an available program, such that the material is not visually distinguishable from other compost and breaks down into carbon dioxide, water, inorganic compounds, and biomass, at a rate consistent with known compostable materials (usually 90 days). These compostable materials leave no toxic residue.

Coroplast Signs

An alternative to bag signs are signs printed on coroplast, a material that resembles corrugated cardboard but is made from plastic. Coroplast signs are cut to size from larger sheets of material and then screen printed. They are displayed in yards by inserting wire stakes into the corrugation in the edge of the sign board and then pressing the other end of the stakes into the ground. Because coroplast signs are printed using a screen print process, it is possible to do four color process printing to obtain amazing full-color results.

Custom Printing

Adding words and/or graphics in one or more colors to the bag

Degradable

A material that undergoes a significant change in its chemical structure under specific environmental conditions resulting in a loss of some physical properties. (Micro-organisms do not need to be involved).

Doorknob Bags

Gauge

The thickness of material. The higher the gauge, the thicker the material.

GMO

GMO, or Genetically Modified Organism, is an organism whose genetic material has been altered using genetic engineering techniques. DNA molecules from different sources are combined into one molecule to create a new set of genes. This DNA is then transferred into an organism, which creates a protein. The protein material is harvested and converted into a material that is used as an alternative to plastic.

Glue Strip

A line of adhesive added to the bag to make it self-sealing...can be permanent or resealable

Grommet

A hang hole reinforced with a metal ring to help keep the bag from tearing

Gusseted Bags

Flat style bag with both sides or bottom tucked in to form gussets. Designated with three dimensions; Side Gusset (width x depth x length) or Bottom Gusset (width x length + gusset). View Gusseted Poly bags.

Hang Hole

A hole is added to the bag, usually near the top, allowing it to hang on a hook or have a tie inserted.

Header Bags

Side-weld bag with continuous seal along top, 2"-3" below fold. Bag is loaded and sealed from the bottom and typically has a hang hole.

High Density Polyethylene

OK Compost and DIN CERTCO EN Certifications

These two types of compost certifications are standard in Europe and are very similar to ASTM D and D. They test to ensure that at least 90% of the organic material is converted into carbon dioxide. Similar to ASTM D, these testing specifications require that no more than 10% residue remains after three months and the resultant compost does not negatively affect plant growth. Although these certifications are the standard in Europe and other regions of the world, we recommend attaining BPI certification if you are using compostable products in the U.S.

Organic

Natural products that have been grown without the use of conventional pesticides and artificial fertilizers, free from contamination by human or industrial waste, and processed without ionizing radiation or food additives. Producers must be certified by an independent third-party certifying agency in order to use the USDA Organic label.

Oxo-Degradable

Often mistakenly called Oxo-Biodegradable, it is a plastic made from fossil fuels that has been treated with an additive that allows it to disintegrate over time through interaction with microbes. The chemical structure of the plastic is broken down with the help of oxygen and heat or sunlight, and then the smaller particles are utilized by micro-organisms as food. They do not pass ASTM regulations, however, because they do not degrade as quickly as the definition requires. They compost well and are safe for landfills.

Back to top

Perforation

A line of small holes placed on a bag to make it easier to tear off or open...can also be used to make a tamper-evident bag

PLA

A type of bioplastic (also known as organic plastic). Polylactic acid or polylactide (PLA) is a form of plastic derived from corn or sugar cane. Starches from the corn and sugar cane are converted into carbon and other elements that are used to make the plastic polylactide.

Plant Starch Cutlery

Made from a type of bioplastic (also known as organic plastic), plant starch material is a biodegradable, thermoplastic resin. It is composed of starch combined with several other biodegradable materials. The cornstarch is modified in order to obtain heat-resistant properties, making the plant starch material one of the few bioplastics capable of withstanding high temperatures.

Pocket

Adding another sheet of plastic to the bag, usually sealed on three sides, to provide additional, separate storage

Polypropylene

Stronger and more rigid than polyethylene. Preserves freshness with vapor and moisture barriers. Non-porous and excellent clarity. Ability to withstand high temperatures.

Process Print

Colors are reproduced by printing overlapping dots of cyan, magenta, yellow, and black (CMYK) inks to simulate a large number of different colors.

Random Print

Tamper-Evident Zipper Lock Bags

Many zipper lock bag users (e.g. retail goods, food products) want to ensure that only their consumer utilizes the resealable zipper in the packaging. One way to accomplish this is to use a tamper-resistant zipper lock bag, which is basically a bottom-fill zipper lock bag that is pre-sealed above the zipper. A perforation in the plastic above the zipper allows the consumer to tear away the seal and access the zipper and the bag contents. Another type of tamper-evident zipper lock bag has a zipper that will not open once it has been closed except by destroying the bag itself.

Tensile Strength

The force required to break through film and bags, or snap rope, cable ties, and wire by pulling on opposite ends. Determined by material thickness and width.

Tubular Bags

Bags with no side seals or slit seals that are usually bottom sealed and have a tail.

UVI

Ultra Violet Inhibitor. Additive diminishes the effect of sunlight breaking up the film and extends film life in sunlight conditions.

Vent Hole

A small hole is added to the bag to allow air and moisture to pass through the bag

Wicketed Bags

Tear-off bags held in place by a metal wicket on the lip of the bag. View Wicketed Poly bags.

Write-on® Area

A white area imprinted on the bag allowing it to be written on

Zipper Lock Bags

Plastic bags can be made with narrow interlocking tracks, made from the same plastic material, that are sealed into the poly bag near the open end across the width. These are called zipper bags, zip lock bags or reclosables. Typically, the user places an item in the bag and then pinches one end of the track near the seal at the side and slides their fingers across the width of the bag, forcing the poly zipper tracks to merge and lock together. Most zipper lock bags can be opened and resealed a number of times.

In the world of power generation, performance and durability are everything. Whether it’s a standby unit for emergencies or a primary power source in remote locations, generators need to operate efficiently and reliably — often under demanding conditions. One critical but often overlooked component in ensuring this reliability is the shroud — specifically, custom poly shrouds.

At Atlantic Poly, Inc., we’ve seen firsthand how properly designed poly shrouds can improve generator cooling, reduce wear and tear, and ultimately extend the life of your equipment.

Optimizing Airflow, Minimizing Heat

Generators produce a tremendous amount of heat during operation. Without proper airflow management, internal temperatures can rise quickly — leading to overheating, system shutdowns, or even permanent damage. A poly shroud helps direct and optimize airflow over and around critical components such as radiators, alternators, and exhaust systems.

Unlike generic or poorly fitted metal housings, custom poly shrouds can be engineered to fit precisely within your system, ensuring that cooling air is delivered exactly where it’s needed most. This kind of targeted airflow boosts efficiency and supports stable, long-term operation.

Why Poly?

Polyethylene and polypropylene materials are lightweight, corrosion-resistant, and easy to mold into complex shapes. This makes them ideal for shrouds that need to fit snugly in tight or uniquely shaped spaces. Unlike metal, poly won’t rust or degrade when exposed to moisture, fuel vapors, or industrial chemicals — which is especially important for outdoor or mobile generator units.

Because poly shrouds are lighter than their metal counterparts, they also reduce overall system weight, making them an excellent choice for portable generators or equipment mounted on vehicles or trailers.

Reducing Maintenance and Downtime

By controlling airflow and shielding critical components from dirt, debris, and moisture, a poly shroud doesn’t just support cooling — it protects your generator from environmental stress. This added protection helps reduce the frequency of maintenance, prevent damage to fan blades or belts, and minimize the risk of sudden failures.

That means less downtime, fewer repair costs, and longer intervals between servicing, all of which contribute to the long-term value of your investment.

Built for Performance — Made to Last

At Atlantic Poly, Inc., we specialize in custom-made poly shrouds that are tailored to your specifications and performance requirements. Whether you're outfitting a new generator system or replacing outdated components, we’ll help you design a solution that improves airflow, supports thermal efficiency, and holds up under pressure.

Ready to Upgrade Your Equipment?

If your generator system could benefit from improved cooling and longer-lasting performance, contact the team at Atlantic Poly, Inc. to learn more about our custom poly shroud capabilities. We’ll help you create a solution that keeps your equipment running cooler, cleaner, and longer.

At Atlantic Poly, Inc., we supply high-quality poly pocket bags designed to meet the demands of industrial, commercial, educational, and office settings. But what exactly are poly pocket bags—and what makes them so widely used?

Pocket bags are clear or colored polyethylene sleeves or pouches used to store, protect, and display documents, labels, instructions, work orders, and small items. They often come with features like adhesive backing, magnetic strips, hook-and-loop closures, or grommets for easy attachment to bins, machines, shelves, or walls. Their primary purpose is to protect documents from dust, dirt, grease, and moisture while keeping important information visible and accessible.

So, why are they so popular?

First, it’s their versatility. Poly pocket bags can be used in manufacturing plants to display safety instructions, in warehouses to label inventory racks, in hospitals to protect patient information, or in schools to organize classroom materials. Their applications are endless, and they can be adapted to almost any environment.

Second, poly pocket bags are durable. Made from tough polyethylene, these bags resist tearing, moisture, and exposure to harsh conditions. Unlike paper folders or vinyl sleeves that break down over time, poly pocket bags hold up even in high-traffic, high-use settings.

Another major reason for their popularity is efficiency. With easy-open flaps, resealable closures, and customizable sizes and formats, these bags help streamline processes. Workers can quickly identify the contents without opening the bag, keeping workflows smooth and organized.

In today’s industries, where compliance, labeling, and information sharing are critical, having a simple, reusable solution like a poly pocket bag can make a big difference. They're a small product with a big impact—and a favorite across sectors for good reason.

When shipping metal components or finished goods across borders, one of the biggest challenges manufacturers face is corrosion. Exposure to fluctuating temperatures, humidity, and salt air during transit can quickly compromise the integrity of valuable parts—especially during ocean freight or long-term storage. That’s where VCI (Vapor Corrosion Inhibitor) bags come in.

At Atlantic Poly, we specialize in providing high-performance VCI bags that do more than just protect—they help your business stay compliant with global shipping standards and avoid costly delays or damaged inventory.

Why Compliance Matters

International shipping requires strict adherence to packaging and material standards, especially for metal goods. Certain export destinations (like the EU, Asia, and the Middle East) have regulations around corrosion protection and environmental safety. Improper packaging not only puts your products at risk but can also result in non-compliance, customs issues, or rejections at the port of entry.

???? How VCI Bags Solve the Problem

Our VCI bags release a safe, invisible vapor that forms a molecular barrier on metal surfaces. This barrier protects against moisture, salt, and other corrosion triggers—without the need for messy oils or greases. The result is clean, dry, and protected parts that meet international shipping requirements and customer expectations.

VCI bags:

  • Protect ferrous and non-ferrous metals
  • Meet MIL-SPEC and ISO standards
  • Eliminate the need for post-shipment cleaning
