Pet Food Packaging: Materials, Bag Types, Recyclability and Printing
Pet food packaging has to protect fats and flavour, withstand shipping and meet the requirements of each sales market. This guide covers materials, bag types, mono-PE design for recyclability, EU PPWR dates and gravure printing.
Before ordering, brands need to know whether a material will protect the food for its intended shelf life, run on their filling equipment and meet local requirements. Repeat orders bring another concern: keeping the printed pack looking consistent.
What does pet food packaging need to do?
A pet food bag has to keep the food safe and fresh through filling, transport and storage. It also needs to work for the person buying and using it. The choice of barrier, strength, format and print should follow the product's requirements.
Materials, inks and adhesives must be suitable for their intended use and the target market, including any potential transfer of substances to the food.
Oxygen, moisture and light can damage fats, vitamins and flavour. High-fat products and long shelf lives need particular attention to barrier performance.
Large dry food bags must withstand stacking, drops and repeated handling. Check both seal strength and the film's resistance to puncture by hard kibble.
Zippers, handles and tear notches can make opening, carrying and resealing easier.
The structure should provide the protection the product needs at a workable cost, while meeting the rules of the sales market.
Which material is best for a dry dog or cat food bag?
The right structure depends on fat content, fill weight, shelf life and any recycling requirements. Dry food bags commonly use laminated films, with layers chosen for printing, protection and heat sealing.
Structure | Barrier: rough comparison | Typical use | Recyclability note |
|---|---|---|---|
PET / PE | Basic | Products with less demanding barrier requirements | Mixed materials; difficult to recycle through conventional PE film streams |
PET / VMPET / PE | Medium to high | Dry food, treats and roll film | Mixed materials; difficult to recycle through conventional PE film streams |
PET / AL / PE | High | Long shelf life and high-fat products | Mixed materials; difficult to recycle through conventional PE film streams |
Mono-PE: PE / PE with a suitable barrier coating or thin barrier layer | Depends on the design | Brands developing a recyclable packaging structure | Can be designed for PE recycling streams; assess the whole pack |
Paper / PE or paper with a barrier layer | Depends on the structure | Treats and packs where a paper finish is wanted | Depends on the full structure and local recovery routes |
These descriptions are a starting point. Performance depends on the films, coatings and thicknesses used. Confirm oxygen and moisture barrier performance for the actual structure, and assess light protection where needed. A material name or this table cannot guarantee shelf life.
Give your supplier the product type, fat content, fill weight and target shelf life. Those details are more useful for choosing a structure than the bag style alone.
What packaging works for wet food and treats?
Tell the supplier how the product is processed. Wet food sterilised after sealing needs a pack suited to that process. Treats often need moisture and oxygen protection, with a closure that works after the pack has been opened.
Wet food: retort pouches
Some wet food is sealed in pouches and then processed in a retort. The film, inks and adhesives must withstand the validated sterilisation process without delamination or leakage. Small, single-serve retort pouches are used for cat food and portion feeding.
For more on seal, laminate and sterilisation checks, see our retort pouch troubleshooting guide.
Freeze-dried and dried treats
Freeze-dried treats absorb moisture readily. Hard pieces or sharp edges can also put stress on a pouch. Depending on the product, check the need for:
A high-barrier structure, which may use metallised film or foil
A reliable zipper for resealing
A small window or no window where light protection is important
Film with suitable puncture resistance
Flat bottom bag or stand-up pouch?
A stand-up pouch is often worth considering for small and medium packs, particularly where cost matters. Flat bottom and quad seal bags are options for larger, heavier packs that need a stable shelf shape and more printable panels. Fill weight, packing equipment and transport testing should decide the final choice.
Flat bottom bags have five printable panels and a stable base. They are common in premium dry food ranges.
Quad seal bags use four corner seals to help hold their shape and are common for heavier dry food packs.
Stand-up pouches offer a flexible format, often with a zipper, for treats and smaller dry food packs.
Three side seal and back seal bags are used for samples, single servings and small treat packs.
Retort pouches are suited to wet food processed by sterilisation after sealing.
Roll film is supplied on reels for a brand's own form-fill-seal equipment.
Our packaging types guide covers the formats in more detail.
Can pet food bags be recyclable?
Pet food bags can be designed for recycling. One option is mono-material polyethylene, usually called mono-PE, where the layers are all or predominantly PE. The barrier layer, adhesives, inks, zipper and other components must also be compatible with the intended recycling stream.
A design that is compatible with recycling still needs a collection and processing route. Check how flexible PE packaging is collected, sorted and reprocessed in each country where the product will be sold.
Moving from a PET-based laminate to mono-PE can change the sealing window, stiffness and heat resistance. Test those properties alongside the barrier. Before switching, ask:
Does the structure protect this product for its target shelf life?
Does it run and seal reliably on the actual packing equipment?
Is flexible PE packaging collected, sorted and recycled in the sales market?
What evidence supports a recyclable claim on the finished pack?
What do the EU PPWR rules mean for pet food packaging?
The EU Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40, entered into force on 11 February 2025 and has applied generally since 12 August 2026. The general recyclability requirement applies from that date. Detailed design criteria, recycled content requirements and harmonised labelling follow on separate timetables.
Requirement | Application date |
|---|---|
General recyclability requirement | From 12 August 2026 |
Design-for-recycling criteria and performance grades | 1 January 2030, or 24 months after the relevant delegated acts enter into force, whichever is later |
Minimum recycled content in plastic packaging | 1 January 2030, or 3 years after the relevant implementing act enters into force, whichever is later |
Harmonised material composition label | 12 August 2028, or 24 months after the relevant implementing acts enter into force, whichever is later |
Recyclability performance grade A or B | From 1 January 2038 |
Under Article 7, the minimum post-consumer recycled content requirement for non-PET contact-sensitive plastic packaging is 10% once the relevant application date is reached, subject to applicable exemptions. It is calculated as an annual average per manufacturing plant, by packaging type and format. Feed packaging falls within the contact-sensitive category, which includes pet food packaging.
The PFAS limits in Article 5(5) concern food-contact packaging. EU law distinguishes food from feed, so this particular provision does not cover pet food packaging. Other applicable chemical restrictions and a customer's own PFAS requirements still need to be checked.
The manufacturer as defined by the PPWR is responsible for the conformity assessment, technical documentation and EU declaration of conformity. For this type of sales packaging, the manufacturer is usually the brand owner or filler. The packaging supplier provides the necessary information, and importers have their own verification duties. The European Commission's PPWR guidance explains these roles and the application of the recyclability requirement.
Compliance needs to be assessed for the actual pack. A mono-PE description alone does not prove that it meets every applicable PPWR requirement.
What rules apply in the United States and the EU?
In the United States, FDA rules on packaging materials also cover pet food packaging. 21 CFR 570.14 makes the food packaging regulations in 21 CFR Parts 174 to 179 applicable to packaging for animal feed and pet food. Ask the supplier for the regulatory status of the materials for the intended use.
In the EU, pet food is legally feed. Regulation (EC) No 178/2002 distinguishes food from feed, and Regulation (EC) No 767/2009 governs the placing on the market and use of feed. Human food-contact rules do not automatically apply in the same way to pet food packaging. The pack must not make the feed unsafe, and relevant packaging, chemical and market-specific requirements still apply.
What should you check in the design before printing?
The brand, pet type, life stage and flavour should be easy to identify. The artwork also needs to fit the bag format and print clearly on the chosen film.
Put the main product information where it can be read easily on the shelf.
Use a visual style that fits the range. Hand-drawn animals and a simple dark palette give different impressions; neither is right for every product.
Leave space for ingredients, feeding instructions, batch coding, the barcode and any QR code.
Check small text and barcodes against the actual background, especially on metallised films or matte finishes.
Agree on the material early. A move to a recyclable design can affect colour, finish and window options.
Why use gravure printing for pet food bags?
Gravure transfers ink from engraved cylinders onto film. Reusing the same cylinders for repeat orders helps reproduce the artwork consistently. Colour also depends on ink viscosity and other press conditions, so cylinder reuse needs to be backed by process control.
Each printing separation usually needs its own cylinder. Photographs and gradients are reproduced by overprinting separations; the number of visible colours in an image is not the cylinder count.
Cylinders can be stored for repeat orders of the same artwork. Confirm the artwork, dimensions and separations before making them. If a design changes, check which cylinders are affected and whether they need to be remade.

Frequently asked questions
What is the best material for dry pet food bags?
It depends on fat content, fill weight and shelf life. Common structures combine a barrier layer, such as metallised film or foil, with a PE sealing layer. Brands developing a recyclable pack can test mono-PE structures against the product's barrier and packing requirements.
Are mono-PE pet food bags recyclable?
They can be designed for PE recycling streams, but the barrier layer, adhesives, inks, zipper and other components affect compatibility. Actual recycling depends on collection, sorting and reprocessing in the sales market. Check those conditions before making a recyclable claim.
Does the EU PPWR apply to pet food packaging?
Yes. Pet food packaging placed on the EU market is covered by the PPWR. The general recyclability requirement applies from 12 August 2026; detailed design-for-recycling and recycled content requirements follow from 2030 or later, depending on the relevant acts. The PFAS limits in Article 5(5) concern food-contact packaging and do not cover feed packaging.
What packaging is used for wet pet food?
Wet pet food is sold in pouches, trays and cans. If it is sterilised after sealing, the packaging materials, inks and adhesives must be suited to the validated process.
Should I choose a flat bottom bag or a stand-up pouch?
A stand-up pouch is often worth considering for smaller packs and cost control. Flat bottom bags are an option for larger, heavier packs where a stable base and more printable panels are useful. Confirm the choice against fill weight, packing equipment and transport testing.
What is the difference between pouches and roll film?
Finished pouches arrive ready for filling and sealing. Roll film arrives on reels and is formed into bags on the brand's own form-fill-seal equipment.
