Liquid milk composite bags appear leakage and broken bag is what reason?

Composite package bags of liquid milk in the production, transportation and sales may discharge, torn bags and other problems. Why will appear the leakage liquid milk packaging, torn bags, leakage, torn bags situations? Liquid milk appear leakage, torn bags cause analysis: one is the poor packaging material tenacity & ndash; — Packaging material brittleness is big, poor toughness, falling in the finished product packaging or by external shocks, easily torn bags in the bag body place; The second is packing material & ndash; poor thermal viscous — Heat sealing just heat sealing good haven't cooling, is the impact of the filling of liquid milk have easy break the heat sealing parts followed, is the poor thermal adhesive strength of packaging materials; Third, poor heat sealing strength in the manufacturing process of finished product packaging & ndash; — Heat sealing seal quality is poorer, under the impact of the liquid milk or from external extrusion, easily occurred in discharge, torn bags. To solve above problems, experts put forward two Suggestions: one is focus on packaging burst pressure, drop resistance, compression performance, heat sealing strength, thermal adhesive strength, tensile strength and elongation at break, the pendulum impact resistance and so on various performance indicators monitoring; The second is to improve the heat sealing machine parameters, the choice has good flexibility and heat sealing performance of packaging material.
