Pet Bag Cardboard Core Holders represent an essential structural component in flexible pet food packaging, combining functionality with sustainability.
These specially engineered cardboard cores provide rigid support for stand-up pet food bags, maintaining shape integrity and enabling easy dispensing of dry pet food, treats, and supplements. Designed to fit perfectly within the bottom gusset of flexible bags, these cores prevent collapse during filling, transportation, and storage while allowing the package to stand securely on retail shelves and in home pantries. Crafted from food-grade, recycled cardboard, they offer a plastic-free alternative to traditional structural supports, helping pet food brands meet sustainability goals without compromising on performance or product protection.
Engineered with a spiral-wound construction that provides exceptional radial strength, these cores prevent bag collapse even when partially full. The rigid structure maintains the bag's shape during handling and transportation, reducing product compaction and ensuring consistent product flow during dispensing. Specialized flaring at the top edges creates a secure interface with bag liners.
Constructed from 100% food-grade recycled cardboard that meets FDA and EU 10/2011 food contact regulations. The materials are free from harmful chemicals, dyes, and adhesives that could migrate into food products. All components are tested to ensure they do not affect the taste, aroma, or safety of pet food products, even during extended storage.
Available in a wide range of diameters (30mm to 100mm) and lengths (80mm to 300mm) to accommodate various bag sizes and product volumes. Precision manufacturing ensures consistent dimensions that fit perfectly with bag sealing equipment, reducing production line jams and ensuring efficient packaging operations. Tapered designs are available for specific dispensing requirements.
Made from 95% post-consumer recycled content with FSC certification verifying responsible sourcing. The cores are fully recyclable and biodegradable, providing a plastic-free structural solution that reduces environmental impact. Water-based adhesives and natural processing ensure the entire component remains eco-friendly throughout its lifecycle.

The most common application, providing structural support for stand-up pouches and bags containing dry dog food of all varieties. The cores maintain bag shape from small 250g treat bags to large 15kg economy packs, ensuring shelf appeal and easy dispensing for pet owners.
Ideal for both dry cat food and specialized treats, these cores fit seamlessly into flexible packaging designs while meeting strict food safety standards. The rigid structure prevents bag punctures from sharp claws when curious cats investigate their food packages.
Perfect for packaging food for rabbits, guinea pigs, hamsters, and other small pets. The precise dimensions work with smaller bag sizes common in this category, while the food-safe materials ensure compatibility with specialized diet formulations.
Provide structural support for bird seed and avian food packaging. The optional moisture-resistant coating protects against humidity that can affect seed quality, while the recyclable construction aligns with the eco-conscious values of many pet owners.
Ensure professional presentation and easy dispensing for pet vitamin and supplement packaging. The rigid core allows for precise pouring of small kibble-sized supplements, reducing waste and mess during feeding.
Our cardboard cores provide critical structural support that maintains bag shape during filling, shipping, and storage. This prevents product compaction and clumping while enabling the bag to stand securely on retail shelves and in home pantries. The rigid structure also makes pouring easier for consumers, reducing spills and waste. Testing shows packages with our cores experience 70% less damage during transportation compared to unsupported bags.
Absolutely. All our pet bag cores are manufactured using FDA-approved food-grade materials and adhesives that meet strict safety standards for direct and indirect food contact. They undergo rigorous testing to ensure they do not transfer chemicals, odors, or tastes to pet food products. Our production facilities maintain food-safe certifications, ensuring no cross-contamination with non-food materials during manufacturing.
Yes, our standard cores are designed to perform in typical home and retail storage environments with normal humidity levels. For high-moisture environments or longer shelf life requirements, we offer an optional plant-based moisture-resistant coating that provides enhanced protection without compromising recyclability. This treatment allows cores to maintain structural integrity in environments up to 85% relative humidity.
Our cardboard cores offer significant environmental advantages over plastic inserts. They contain 95% recycled content compared to plastic's typical 0-30% recycled content. Cardboard cores reduce transportation weight by up to 60%, lowering carbon emissions during shipping. At end-of-life, they are fully recyclable through standard paper recycling streams and will biodegrade in 8-12 weeks if discarded, compared to plastic inserts which can take 450+ years to decompose.
We offer extensive customization including precise diameter and length matching to your bag specifications, wall thickness adjustments for different weight requirements, and specialized features like vent holes for moisture regulation or tapered ends for easier insertion during bag manufacturing. For brand differentiation, we can incorporate subtle branding elements using food-safe inks that won't compromise safety or recyclability.
