Materials
In my work with potato chip packaging, we always use a multi-layer composite structure, and every layer has passed food-grade safety tests. Here's what each part does:
The outer layer is PET. It gives the bag a clean, glossy look, and it's strong enough to resist stretching, so bags don't tear or deform easily during shipping and handling.
For the barrier layer, we offer two options. Aluminum foil (AL) provides the best protection, with oxygen permeability ≤0.1cc/㎡/24h and moisture permeability ≤0.1g/㎡/24h. It completely blocks light and air, which helps extend the shelf life of chips by 3 to 6 months. We also have VMPET, an aluminized PET film, which works well for keeping moisture out at a more cost-effective level.
The inner layer is food-safe PE. It's non-toxic and tasteless, with a heat-sealing temperature between 120–160°C and sealing strength ≥30N/15mm, so the seal stays tight and doesn't leak air.
Bag Advantages
These chip bags use a back-seal structure, which I really recommend for efficiency. It leaves the front completely clean, maximizes printing area, and lets your brand design and product images show fully without interruption.
We also add an easy-tear notch - slightly serrated, so kids and seniors can open it without struggle. For better preservation, we can include a resealable zipper. Once opened, customers can seal the bag again to keep chips from getting soggy and soft.
Product qualification
We run both digital and gravure printing lines, so we can handle almost any MOQ. Whether you need 500 pieces, 10,000, or more, we can customize everything to your needs. If you're interested in this style of potato chip packaging pouch, feel free to send us an inquiry.
