Pet Food Packaging Bag Manufacturers

Pet Food Packaging Bags Built Around Your Filling Line and Shelf Life Target

SC Shanghai New Material Tech. Co.,Ltd. (Shengchang) manufactures high-performance flexible packaging for dry kibble, semi-moist treats, freeze-dried products and bird feed. Our Pet Food Packaging Bag range covers 1 kg boutique packs through 20 kg bulk distribution bags, produced on multi-layer co-extrusion film lines in Shanghai.

We work from the working point: product form, fill weight, target shelf life, transport route and the sealing jaws on your line. Material structure, thickness, sealant layer and closure type are then fixed before printing plates are cut.

Our Pet Food Packaging Bag Range

Three formats cover most pet food projects. Each one balances barrier performance, structural rigidity and cost differently, so the choice usually follows pack weight and retail channel.

The 1–3 kg Flat Bottom Pouch Bag for Dog Treat uses an eight-side seal construction that distributes weight evenly and holds a box-like shape on shelf. For larger volumes, the 5kg, 10kg, 15kg Slider Zipper Pouch Bag for Dog Treat adds a nylon layer for toughness during pallet handling.

Barrier Engineering for Kibble, Treats and Freeze-Dried Products

Rancidity, caking and aroma loss in pet food are driven by oxygen and moisture ingress. We select the barrier layer against the fat content, water activity and expected storage window of the product rather than applying one structure across the range.

• Aluminium foil laminates for long shelf life and light-sensitive formulations.
• VMPET metallised structures where a balance of barrier and cost is required.
• PA/EVOH/PE co-extruded films for high oxygen barrier without foil, including retort and vacuum adjacent duties.
• Nylon-reinforced sealant layers for bone-in or abrasive contents that risk puncturing the pouch.

Related structures from our wider range include Multi-layer Co-extruded Film at 7, 9 and 11 layers, and Mono-Material Package constructions for recyclability programmes.

Closures, Fitments and Handling Features

Closure choice affects both the filling operation and how the end user lives with the pack. We confirm the closure at quotation stage so the bag geometry, seal width and film thickness are consistent.

• Slider zippers for 5–15 kg packs opened repeatedly by hand.
• Press-to-close zippers and tear notches for retail treat packs.
• Reinforced side gussets and flat bottoms for stacking stability.
• Airplane holes, handle cut-outs and degassing options where the product requires them.

Printing, Branding and Custom Structures

Custom printing is standard across the pet food range. We print logos, nutritional panels, batch coding areas and brand colour schemes in high resolution, with matte, gloss or metallic finishes. Artwork is supplied as .pdf or .ai files, and we check colour separation and bleed before plates are produced.

For launches and test markets, Digital Printing-Low MOQ allows short runs without cylinder investment. Gravure cylinders are quoted separately for repeat production volumes.

Production Capacity and Quality Control

Our Shanghai plant runs two printing lines with a daily output of 550,000 packaging bags and 2,500 tonnes of roll film. All plastic pellets are 100% new food-grade material, and production is controlled under ISO 9001, HACCP, BRC and GMP systems.

• Physical testing: tensile strength, puncture resistance and seal strength.
• Chemical testing: material composition and gas barrier performance.
• Environmental simulation: freezing, vacuum and transport simulation.
• Traceability: batch-level records from raw material to finished pouch, with inspection reports available per batch.

Information We Use to Configure Your Solution

A workable proposal needs the following inputs. Where a value is still open, we propose a starting structure and confirm it against a sample.

Delivery, Documentation and Ongoing Supply

Standard production lead time for pet food pouches is 15–18 days after artwork and deposit confirmation. Cylinders are quoted at USD 110 per colour. MOQ is 10,000 pcs for flat bottom pouches and 5,000 pcs for slider zipper bags; digital printing supports lower launch quantities.

Our factory is 50 km from Shanghai Port, so sea freight is the usual route, with air freight available for urgent batches. Payment terms are 30% deposit before production and 70% balance before delivery, by T/T or L/C. Reorders run against the retained cylinder and approved sample, which keeps colour and seal performance consistent between batches.

Frequently Asked Questions

What pack sizes can you produce for pet food?

We cover 1 kg to 20 kg. Flat bottom pouches suit 1–5 kg treats, slider zipper pouches suit 5, 10 and 15 kg dog food, and stand-up pouches suit 1–5 kg including frozen dog food. Dimensions are customised to your filling line.

Which material should I choose for long shelf life?

For maximum oxygen and light protection we use PET/AL/PE or PET/AL/nylon/PE laminates. Where foil is not required, PA/EVOH/PE co-extruded structures deliver high barrier with better puncture resistance and recyclability options.

Can you supply recyclable pet food packaging?

Yes. Our Mono-Material Package range uses PE-based structures designed for recycling streams, and we can review barrier requirements against a mono-material construction before committing to a laminate.

What is the minimum order quantity?

MOQ is 10,000 pcs for flat bottom pouches and 5,000 pcs for slider zipper bags. Digital Printing-Low MOQ supports smaller launch volumes without cylinder investment.

How do you verify quality before shipment?

Each process stage is inspected, and finished pouches are checked 100% against customer requirements and international standards. Physical, chemical and environmental simulation tests are recorded, and batch inspection reports are available.

Do you provide samples before mass production?

We produce pre-production samples from the agreed structure and artwork so seal strength, barrier performance and print colour can be confirmed before the full run is released.
