The liquid detergent stereo bag packaging material selection
Liquid detergent stereo bag packaging requirements: high strength, impact resistance, resistance to burst good rigidity, good barrier property, can stand firm, stress cracking resistance, good sealing.
Liquid detergent stereo bag design structure:
(1) the three-dimensional: BOPA/LLDPE;Bottom: BOPA/LLDPE.
(2) 3 d: BOPA/strengthen BOPP/LLDPE;Bottom: BOPA/LLDPE.
(3) 3 d: PET/BOPA/strengthen BOPP/LLDPE;Bottom: BOPA/LLDPE.
Liquid detergent stereo bag design reason: the good barrier property structure, material big rigidity, suitable for three-dimensional 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.
