Composite bag

Composite bags are suitable for vacuum or general packaging of food, electronic products, chemicals, pharmaceuticals, tea, precision instruments, and defense‑related items. They offer advantages such as high strength, corrosion resistance, excellent tear resistance, non‑toxicity and odorlessness, moisture resistance, light impermeability, UV protection, and antistatic properties, making them widely applicable to the packaging of powders and granular materials. Production processes include side‑seal bags, bottom‑seal bags, center‑seal bags, and three‑side‑seal bags; material options comprise two‑layer laminates of BOPP/LLDPE. Common raw materials include OPP, PE, POF, PPE, and PP.
