Compostable packaging is no longer just a passing trend or relegated to the select few companies that can afford it. Both big industry players and startup companies alike are setting the bar high and choosing compostable packaging materials for their products. Today we're hosting a Q&A about compostable films with Dave Meacham, Packaging Strategist for film supplier partner Eagle Flexible Packaging.

Compostable flexible packaging is comprised of cellulose or plant-derived materials. By its very nature, cellulose is:
A company can choose to use 100% compostable packaging materials or can go for a hybrid approach, replacing some film components or layers with renewable materials. Your film supplier will be able to guide you in the right direction as to which option is best for your product attributes and desired functionality.
A. When we build compostable flexible packaging structures to replace traditional structures, our goal is to match the shelf life requirements of the traditional structure. Meaning: compostable structures will have the same shelf life compared to traditional structures.
A. No. Once film is converted and product is secured into the package, the shelf life is not compromised. The material is designed to only degrade or break-down in a compost environment.
A. There are many variables that go into each specific project; minimums are dependent on the number of impressions or desired size of the package and the custom film structures needed specific to the project. Generally we have a 500 lb. minimum outside of a trial which equates to one small roll of film, depending on the size of the project itself.
A. Though prices vary depending on the specifics of the project, generally compostable material prices are at least double the amount of traditional flexible packaging. As the demand continues to grow for compostable packaging, we believe we will see prices come down.
Companies today often don't have a problem with their consumers seeing the additional cost of green packaging as value-added, especially if they fit any of the following situations:
A. Yes! In fact, cellulose packaging was the first clear packaging, created over 100 years ago.
A. Anytime is a great time, however we strongly recommend adopting compostable packaging from the get-go if possible, or when introducing a new product to your lineup. This way, there isn't as much 'sticker shock' when comparing compostable to traditional flexible packaging.
A. Absolutely. Modern packaging equipment, like VFFS orpremade pouch machinery from Viking Masek, can accommodate today's green, compostable, and recyclable packaging films with ease.

Here are the main criteria to consider and questions to ask when selecting plastic film for industrial packaging:
The type of load:
What type of product are you wrapping? Is it a dry or wet product? What’s its size and weight? Select film thickness, width, and length according to the size and weight of your products. Also, take into account how smooth they are and possible sharp corners that could tear the film.
The type of plastic:
This depends on the nature of the product to be packed. Commonly used plastics include polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), and polyethylene terephthalate (PET). Each has different properties in terms of strength, transparency, and flexibility.
Desired function:
What will your film be used for? Packaging, protection, heat retention, sealing, etc.?
Some films have specific properties that make them resistant to chemicals, UV, or heat. Others are more transparent. Some also have electrical conductivity properties.
Duration of use:
How long do you expect your film to last, whether in transit or in long-term storage?
Respect for the environment:
More and more plastic films are recyclable or biodegradable. Naturally, we advise you to opt for this type of product for obvious environmental reasons.
In industrial applications, several types of plastic film are used, depending on their specific properties and applications. Here are some of the types of plastic film commonly used:
Stretch film
Stretch film is a versatile material, often made from extruded polyethylene in one or more layers, depending on its intended use. It is known for its flexibility as it can stretch from 125% to 500% of its original length.
There are two main types of stretch film, depending on the extrusion technique used.

Plastic film is a versatile product whose properties are largely influenced by the plastic of which it is made. Here are the main plastics used in the manufacture of plastic film:
Polyethylene (PE)
It is one of the most commonly used plastics in industry. It can be produced in single-layer or coextruded versions to meet a variety of needs. It shrinks at temperatures of around 150°C.
There are two types of PE: low-density polyethylene (LDPE) and high-density polyethylene (HDPE). PE film is generally 40 to 50 micrometers thick, but thinner versions are available, notably LDPE, which also has non-stick and anti-slip properties.
Advantages:
Applications:
The color of the plastic film is an essential aspect of the packaging. Each color has its own specific use. The color you choose will depend on the company’s needs, the type of products packed, and the environments in which these products are stored or transported.
Transparent film
This is particularly useful for identifying packaged products. In a warehousing or production environment, transparency means you can quickly see which products are contained on pallets without having to remove the film. This improves efficiency and inventory management.
Black film
This provides effective protection against light. It is therefore used to protect light-sensitive products (photosensitive materials, chemicals). In addition, black plastic film offers a degree of privacy, as it conceals the pallet’s contents.
White film
This is similar to black film in terms of light protection. It has the added advantage of effectively protecting products from UV rays. This feature is important for products that could be damaged by prolonged exposure to the sun.
Translucent blue film
This film is commonly used in food packaging. The color blue is often associated with freshness and food safety, making it a popular choice for products intended for human consumption.
Other plastic film colors can be used to help identify products in a storage environment, allowing them to be distinguished at a glance and saving time during order picking. Red, for example, is one of these colors.
Cost can vary considerably depending on film type, thickness, and material. Here are some price estimates for the three main types of film:
Stretch film
Stretch film prices can range from 3 euros to over 100 euros per roll.
For film that is applied manually, prices range from 3 euros to over 50 euros, depending on the size of the roll. Less expensive film is generally suitable for light loads, while more expensive film is suitable for heavier loads or specific uses.
If you wish to apply your film with a wrapping machine, prices range from 30 euros to over 90 euros per roll.
Shrink film
Shrink film is available at prices ranging from 20 euros to over 400 euros per roll.
The price difference depends mainly on the width of the roll (prices increase with width) and the thickness of the film.
Examples:
Bubble wrap
Bubble wrap ranges in price from 3 euros to 100 euros for a roll approximately 1 meter long.
