Retort pouch, biscuit packaging and packing bags of laundry detergent material structure

According to different packaging contents and different USES, composite packaging material structure also each are not identical, retort pouch, biscuit packaging and laundry detergent packing bag is our common several kinds of composite packaging products in the life. A 1, packaging requirements, cooking bags used in meat, poultry and other composite bags, request packaging good barrier property, resistance to bone puncture, under the condition of cooking sterilization is not broken, no crack, no contraction, no peculiar smell. 2, design structure transparent: BOPA/CPP, PET/CPP, PET/BOPA/CPP, BOPA/PVDC/CPP, PET/PVDC/CPP, GL - PET/BOPA/CPP。 Aluminum foil: PET/AL/CPP, PA/AL/CPP, PET/PA/AL/CPP, PET/AL/PA/CPP. 3, design for PET: high temperature resistance, good rigidity, good printing ability and strength. PA: high temperature resistance, strength, flexibility, good barrier property and durability. AL: best barrier property, resistance to high temperature. CPP: for high-temperature cooking level, good heat sealing, avirulent insipidity. PVDC: blocking materials. GL - PET: steaming ceramic coating, good barrier property and microwave. For a specific product to choose the right structure, the most transparent tape used for cooking, aluminum foil bags available in high-temperature cooking. Second, biscuits packaging 1, packaging requirements good barrier property, shading resistant, oil resistant, high strength, odourless, tasteless, crisp packaging. 2, the design structure of BOPP/EXPE/VMPET/EXPE/S - CPP。 3, the design for BOPP, good rigidity, good printing eligibility and low cost. Oxygen VMPET: good barrier property, avoid light resistance, water resistance. S - CPP ( Modified CPP) : good low-temperature heat sealing, oil resistant. Three, laundry detergent, self-supporting bag 1, packaging requirements, high strength, impact resistance, crack resistance, good barrier property, good rigidity can stand, stress cracking resistance, good sealing property. 2, 3 d design structures: BOPA/LLDPE; Bottom: BOPA/LLDPE. Stereo: BOPA/strengthen BOPP/LLDPE; Bottom: BOPA/LLDPE. Stereo: PET/BOPA/strengthen BOPP/LLDPE; Bottom: BOPA/LLDPE. 3, the design for the structure of good barrier property, material big rigidity, suitable for self-reliance bags, flexible at the bottom of the well is suitable for processing. Lining for the modified PE, good sealing dirty. Strengthen the BOPP increased mechanical strength, and strengthen the material blocking performance. PET can improve the water resistance and mechanical strength.
