Plastic hose heat sealing tail new process
Kalix, a packaging machine manufacturer, recently invented a new process that solves the problem of collapsing deformation of plastic hoses at the end of heat sealing.
With this technology, after the product is filled in the hose, the sealing legs are rounded, so that the appearance of the product can be more harmonious and beautiful. This new process can also be applied to softer hoses and thinner walls, so the cost can be lower. At the same time, the filling capacity of the product can still be guaranteed without changing the length and width of the hose.
PP plastic, also known as polypropylene plastic, is another fine resin varieties, following the development of nylon, which is a semi-crystalline materials, the advantage is obvious, with excellent mechanical properties and heat resistance, with a high not hydrophilic sex, almost non-absorbent. The disadvantage is poor low temperature impact resistance, easier to aging. However, for comparison PE plastic having a higher melting point.
PE plastic is polyethylene plastic, its corrosion resistance and electrical insulation are very strong. Rigid hardness and strength are relatively high, and the same PP plastic, it also very small water absorption.
Polycarbonate (referred PC) is a polymer molecular chain containing a carbonate group, an ester group according to the structure can be divided into aliphatic, aromatic, aliphatic - aromatic and other types. Which due to the aliphatic and aliphatic - aromatic polycarbonate lower mechanical properties, thereby limiting its application in engineering terms. Currently, only the aromatic polycarbonate obtained industrial production. Due to the special nature of the polycarbonate structure, it has now become the top five fastest growing engineering plastics in general engineering plastics.
