Compostable Deli Storage Bags: A Sustainable Solution for Meat, Seafood and Dairy

As businesses and consumers look for practical alternatives to conventional plastic packaging, compostable deli storage bags are becoming an increasingly relevant option for food storage and retail applications. Delis, butchers, seafood retailers, supermarkets and food businesses need packaging that can provide reliable protection while also supporting their sustainability goals.

Biotuff offers compostable and biodegradable bag solutions made using plant-based materials, providing an alternative to conventional plastic bags for a range of food and storage applications.

What Are Compostable Deli Storage Bags?

Compostable deli storage bags are bags designed to provide a practical way to store or package food while being made from materials that can break down through appropriate composting processes.

Unlike traditional plastic bags, which can remain in the environment for long periods, certified compostable products are designed to break down under specified composting conditions.

However, it is important to select the right bag for the intended application. Food packaging must be fit for purpose, and businesses should confirm that the particular product is suitable for the food, moisture, temperature and storage conditions involved. Food Standards Australia New Zealand recommends using packaging that is suitable for its intended purpose and does not create a risk of food contamination.

Benefits of Compostable Deli Storage Bags

1. An Alternative to Conventional Plastic

Traditional single-use plastic packaging can create significant waste challenges. Compostable alternatives can help businesses reduce their reliance on conventional plastic where a suitable certified product is available.

Biotuff products are manufactured using plant-based, compostable materials, including thermoplastic corn starch resins. The Biotuff range includes food storage and resealable bags designed for practical everyday use.

2. Practical Food Storage

Deli and food-storage packaging needs to do more than look sustainable. It must perform during handling, transportation and storage.

Depending on the product specification, compostable bags can provide useful characteristics such as tear and puncture resistance, leak resistance and moisture and odour control. Biotuff existing food-storage products are designed for applications including fresh food, meat, fish and other food products.

3. Supports More Sustainable Packaging Programs

For food retailers and businesses working to reduce their environmental impact, switching suitable packaging applications away from conventional plastic can form part of a broader sustainability strategy.

Certified compostable products can also support organic-waste diversion where the product is accepted by the relevant composting or FOGO system. Businesses should always check local requirements before placing compostable packaging into a waste stream.

4. Suitable for Different Food Applications

Compostable bags can have applications across different areas of the food industry, including:

• Delis and food counters
• Butchers and meat retailers
• Seafood retailers
• Supermarkets and grocery stores
• Bakers and food producers
• Fresh-food storage
• Household food storage
• Food preparation and portioning

The correct bag should always be selected according to the specific food-contact and performance requirements of the application.

Compostable Bags and Fatty or Acidic Foods

Meat, seafood and dairy products can present particular packaging challenges because they may contain fats, oils, moisture and, depending on the product, acidic components.

This means businesses should not assume that every compostable bag is suitable for every food product. The Western Australian Government specifically advises businesses supplying wet and oily products to confirm with their supplier that the compostable barrier bag is functional and suitable for the intended product.

For this reason, fatty food simulant testing and acidic food simulant testing are important considerations when evaluating compostable deli storage bags for food-contact applications.

Fatty and Acidic Food Simulant Testing

Food simulants are used in laboratory testing to represent certain characteristics of foods and to assess the potential migration of substances from packaging materials into food under specified test conditions.

For compostable deli storage bags intended for applications involving meat, dairy and seafood, the relevant testing and compliance documentation should be reviewed against the intended food types and conditions of use.

According to the test information provided for the product, the bag has passed a migration compliance test using 3% acetic acid at 40°C for 10 days.

This result relates specifically to the stated acidic food simulant and test conditions. It should not automatically be interpreted as proof of compliance for every fatty food application or as evidence that all applicable food-contact requirements have been satisfied.

Where fatty food simulants are relevant, businesses should obtain and review the corresponding migration testing report. Testing should reflect the intended food-contact conditions, including the type of food, contact time and temperature.

These checks are particularly important for businesses looking at compostable packaging for meat, seafood and dairy applications.

Food-Contact Compliance and Testing Standards

When selecting compostable deli storage bags, businesses should consider both compostability certification and food-contact compliance. These are separate requirements: compostability relates to how a product breaks down under specified conditions, while food-contact compliance addresses its suitability for contact with food.

Relevant standards and regulatory frameworks may include:

• AS 2070: Australian requirements and guidance relating to plastics materials for food contact.
• EU Regulation 1935/2004: The European Union's general framework for materials and articles intended to come into contact with food.
• EU Regulation 10/2011: Specific requirements for plastic materials and articles intended to come into contact with food, including applicable migration testing requirements.

For relevant products and markets, businesses may need a migration testing report covering the appropriate food simulants, including fatty food simulants where applicable. They should also obtain the relevant Declaration of Compliance or supporting food-contact compliance documentation, as required by the applicable regulatory framework.

For the new Biotuff deli storage bags, the stated 3% acetic acid test result at 40°C for 10 days can be included as a specific test outcome. Any additional claims relating to fatty food simulants, AS 2070 or European regulatory compliance should be supported by the corresponding reports, declarations and technical documentation.

Businesses should confirm the precise requirements applicable to the material, product type and intended market with their packaging supplier and relevant compliance specialists.

What Is Changing in Western Australia?

Western Australia is continuing to expand its restrictions on non-compostable plastic barrier bags.

From 1 October 2026, restrictions extend to non-compostable plastic barrier bags used for loose or unpackaged meat, seafood and dairy products. The WA Government has established a design standard for compliant compostable barrier bags as part of this transition.

For businesses operating in Western Australia, this change makes it important to review existing packaging and identify suitable alternatives before supplying affected products.

Importantly, the regulations do not mean that every food-storage bag automatically needs to be replaced with a compostable product. The specific use, packaging format and applicable exemption or requirement need to be considered.

In addition to compostability and barrier-bag design requirements, food businesses should evaluate the food-contact suitability of their selected packaging, particularly when it is intended for wet, oily or acidic products.

Preparing for the South Australian Market

As Biotuff prepares to introduce its new compostable deli storage bags into South Australia, food-contact testing and supporting technical documentation will be important parts of the product's market-readiness process.

Supermarkets, deli operators, butchers and seafood retailers should consider the requirements applicable to their particular packaging applications, alongside any relevant state-based plastic restrictions.

Migration testing documentation, including reports for the appropriate food simulants, can help businesses assess whether a bag is suitable for its intended use. Depending on the product and applicable requirements, relevant documentation may include testing under AS 2070 and/or the applicable European food-contact framework, including EU Regulations 1935/2004 and 10/2011.

These standards and regulations should not be treated as automatically interchangeable or as universally mandatory for every Australian application. The specific requirements should be confirmed for the product, intended use and market.

By addressing both compostability and food-contact performance, Biotuff can help prospective customers evaluate packaging options for their operational and sustainability needs.

Why Choose Certified Compostable Bags?

The word "compostable" should not be treated as a generic environmental claim. Businesses should look for appropriate certification and verify that the product meets the requirements for its intended application.

Biotuff states that its compostable products meet recognised Australian and international compostability standards, including AS 4736 and AS 5810 for relevant products.

Certification helps businesses make more informed packaging decisions and understand how a product is intended to perform at end of life.

For food-contact applications, compostability certification should be considered separately from migration testing and food-contact compliance documentation. A product's suitability should be assessed using the relevant evidence for both its intended use and end-of-life treatment.

A Practical Step Towards Sustainable Food Packaging

For delis, butchers, seafood retailers and food businesses, moving away from conventional plastic does not have to mean compromising on practicality.

Compostable deli storage bags can provide an alternative for appropriate food-storage and packaging applications while supporting wider efforts to reduce conventional plastic use.

As Western Australia's barrier-bag requirements expand from 1 October 2026, businesses should review their current packaging, understand the applicable requirements and speak with suppliers about certified, fit-for-purpose alternatives.

With the introduction of its new deli storage bags, Biotuff aims to provide food businesses with additional packaging options for meat, seafood and dairy applications. By combining appropriate compostability credentials with documented food-contact testing and performance, these products can be evaluated against the practical and regulatory needs of Australian retailers.

Biotuff continues to develop compostable packaging solutions designed to help Australian businesses and households make more sustainable choices without sacrificing everyday convenience.
