Cleaner stereo bag and pesticide packaging material structure

1, liquid detergent three-dimensional bag product requirements: high strength, impact resistance, resistance to burst good rigidity, good barrier property, can stand firm, stress cracking resistance, good sealing. Design: (1) the three-dimensional BOPA BOPA/LLDPE/LLDPE bottom (2) the three-dimensional BOPA BOPA/LLDPE/strengthen BOPP/LLDPE bottom (3) 3 d PET/BOPA enhance bottom BOPA BOPP/LLDPE/LLDPE/reason: good barrier property, the 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. 2, pesticide packaging pesticides into insect repellents, pesticides and herbicides, form is divided into granular, powder and liquid, due to the low before two kinds of packaging requirements, the following only for liquid pesticide design structure. Product requirements: because of the highly toxic pesticides which cause serious damage to physical and environmental security, for packaging requirements high strength, good toughness and impact resistance, resistance to drop, sealed well. Design: BOPA/VMPET/S - Reason: CPP design BOPA flexibility, good resistance to Pierce, high strength, good printing. VMPET, high strength, good barrier property type can be used to increase thickening of coating materials. S - CPP to provide heat sealing, barrier property, corrosion resistance, using the ternary copolymer PP. Or use multilayer co-extrusion high separation EVOH, PA layer of CPP. Adhesive: appropriate USES big polarity, cohesion, and high degree of crystallinity of the adhesive. The gluing quantity up to 4 / m2 for beautiful, because there are many types of pesticides, solvents, such as toluene, xylene, ethanol, DMF, mixed solvents, etc. Pesticide ingredients themselves complex, and strong corrosive, should test the adhesive used in advance. Commonly used brand UK3640 / UK6800, LY 50个虚拟现实/ LY - 50 VRH and so on. 3, heavy bags product requirements: the packaging is used for agricultural products such as rice, beans, chemical products ( Such as chemical fertilizers) Such as packaging, the main requirement is strong toughness, good barrier property of necessary. Design: PE/PP/plastic fabric, PE/paper/PE / / PE, plastic fabric, PE/PE design reason: PE to provide sealing, good flexibility, high resistance to drop, plastic fabric strength.
