Fully Degradable Poly Bag

The fully degradable poly bag, commonly known as a "bone bag," is a small-sized eco-friendly flat bag made from bio-based biodegradable materials such as PLA, PBAT, and starch blends. It features an open-top design and fully degrades into CO₂, water, and biomass under industrial composting conditions, leaving no harmful residues. It is an ideal eco-friendly alternative to traditional PE bone bags.

The bag is produced through blown film extrusion, offering high transparency. Its small size and low cost make it suitable for portioning and packaging small items. Sealing can be done easily with a heat sealer or twist tie.

Compared to traditional PE bone bags, it is made from renewable plant-based resources like corn and cassava instead of petroleum-based materials, reducing carbon footprint at the source. Widely used for fresh food packaging, small accessory portioning, pharmaceutical pellet packaging, and household use — it is one of the easiest products for eco-friendly upgrades.

Usage Notes

Store in a cool, dry place away from high temperature, high humidity, and direct sunlight to prevent moisture absorption or premature degradation.

Do not exceed the bag's designed weight capacity. Bone bags have limited load-bearing capability and are not suitable for heavy items.

Do not place hot items exceeding 60°C into the bag to prevent softening or deformation.

FAQ

Q. Why choose 300gsm paper over standard 120gsm kraft paper?

300gsm paper provides a rigid, box-like structure that enhances the perceived value of your product. It doesn't wrinkle easily and can be reused dozens of times, acting as a walking billboard for your brand.
