Kraft Paper Laminated Bags

Kraft paper is brownish yellow and has a wide range of uses, and is often used to make paper bags. The thickness ranges from 80 g/m2 to 120 g/m2. Kraft paper has high burst resistance and can withstand greater tension and pressure without breaking.

PE (polyethylene) has high heat sealing strength so it's generally used as heat sealing layer of laminated materials. Good resistance to oil, acid, alkali and chemicals and good cold and heat resistance.

PET ( polyethylene terephthalate ) is a widely used printing material and cannot be used as a heat-sealing layer material.

PET has good transparency, resistance to low and high temperatures, melting point of 264°C, not easy to wrinkle when sealing, good flatness, especially suitable for automatic packaging machines.
