1. Why Flexible Packaging for Pet Food?

The global pet food market reached $130+ billion in 2025, with flexible packaging becoming the dominant format for dry pet food and treats. Here's why leading brands are making the switch.

1.1 The Shift from Rigid to Flexible

Traditional pet food packaging—cardboard boxes and tin cans—is rapidly being replaced by flexible pouches. The reasons are compelling: better barrier properties, lighter weight for shipping, superior branding opportunities, and improved sustainability profiles.

2. Pet Food Categories & Packaging Requirements

Different pet food types have vastly different packaging needs. Understanding these requirements is crucial for selecting the right packaging solution.

Figure 1: Pet Food Categories & Their Packaging Requirements

2.1 Dry Food (Kibble)

Dry pet food is the largest category, requiring packaging that protects against moisture absorption, oxygen exposure, and pest infiltration. Flat bottom bags are ideal for larger formats (5-25kg), while stand-up pouches work well for smaller portions.

• High moisture barrier (WVTR < 1 g/m²/day)

• Puncture resistance for sharp kibble edges

• Reinforced seals for heavy-duty applications

2.2 Wet Food

Wet pet food requires retort-capable packaging that can withstand high-temperature sterilization. Aluminum foil laminates provide the ultimate barrier for shelf-stable wet food.

2.3 Treats & Snacks

Pet treats prioritize aroma preservation and convenience. Resealable zippers are essential, and clear windows allow pet owners to see the product quality.

3. Barrier Protection Essentials

Pet food packaging must protect against multiple environmental factors to maintain freshness and nutritional value throughout the product's shelf life.

4. Material Options for Pet Food Bags

Choosing the right material structure depends on your product's specific requirements, brand positioning, and sustainability goals.

Figure 3: Pet Food Packaging Material Options

4.1 Multi-Layer Laminate

Structure: PET / AL or VMPET / NY / PE

The industry standard for dry pet food. Offers maximum barrier protection, excellent puncture resistance, and superior print quality. Ideal for large format kibble bags.

Best for: Premium kibble, performance diets, 5-25kg bags

4.2 Aluminum Foil Laminate

Structure: PET / AL / NY / CPP (retort capable)

Provides 100% barrier against oxygen and moisture. Essential for wet food, retort pouches, and products requiring extended shelf life.

Best for: Wet food, semi-moist treats, retort applications

4.3 Mono-PE Recyclable

Structure: MDO-PE / EVOH / PE (100% polyethylene)

The future of sustainable pet food packaging. Store drop-off recyclable while maintaining high barrier performance. Increasingly required by major retailers and regulations.

Best for: Eco-conscious brands, European markets, sustainability leaders

4.4 Kraft Paper + Liner

Structure: Kraft Paper / PET / PE or recyclable PE liner

Natural, premium appearance that appeals to organic and natural pet food brands. The kraft exterior communicates authenticity while the interior liner provides necessary barrier protection.

Best for: Organic brands, natural pet food, artisanal treats

11. Frequently Asked Questions

Q1: What is the shelf life of pet food in flexible packaging?

A: With proper barrier materials, dry pet food can maintain freshness for 12-18 months. Wet food in retort pouches can last 24+ months. The key factors are oxygen transmission rate (OTR), moisture vapor transmission rate (WVTR), and proper sealing.

Q2: Can flat bottom bags handle heavy pet food (10kg+)?

A: Yes! Our heavy-duty flat bottom bags are designed for loads up to 25kg. They feature reinforced corner seals, thicker laminate structures, and optional carry handles for consumer convenience.

Q3: What printing options are available?

A: We offer rotogravure printing (up to 10 colors, best for high volume), digital printing (ideal for short runs, SKU variety, and low MOQ), and flexographic printing. Finishes include matte, gloss, soft-touch, and spot UV.

Q4: Are your pet food bags child-resistant?

A: We offer child-resistant zipper options for pet medications and supplements. Standard zippers are pet-proof (slider zippers are harder for pets to open than press-to-close).

Q5: Can I get recyclable packaging that still has good barrier properties?

A: Absolutely. Our mono-PE recyclable structures with EVOH barrier layer achieve OTR and WVTR performance comparable to traditional multi-material laminates. They're certified for store drop-off recycling.

Q6: What's the minimum order for custom printed bags?

A: For rotogravure printing: 5,000 units minimum. For digital printing: as low as 1,000 units with no plate/cylinder costs. We also offer stock bags with no MOQ for testing.

Q7: Do you offer retort pouches for wet pet food?

A: Yes. Our retort pouches withstand 121°C sterilization and are available in stand-up, three-side seal, and spout pouch formats. We also offer retort-capable recyclable options (PP-based mono-material).

Q8: How do I know what size bag I need?

A: Send us a sample of your product with target weight. We'll recommend optimal dimensions and provide free samples for testing before production. Our engineering team can also conduct fill tests at our facility.
