Production of O-shaped self-adhering air-isolated packing bag

Abstract

A method for preparing the air-isolating 3D packing bag from O-type self-adhering film features that on the basis of the self-sucking performance of self-adhering film and the characteristics of print isolating device, a series of dedicated thermal sealing apparatuses is used for simple and local thermal adhering and sealing and the distributing technique of supplying trunk is also used. The resultant packing bag has high resistance to squeeze, vibration and impact and excellent buffering performance.

Description

technical field [0001] The invention relates to a method for manufacturing an O-shaped self-adhesive film air-rejecting three-dimensional packaging bag. The packaging bag manufactured by the method can be used in electronic products, glassware, precision instruments, handicrafts and other precious and fragile products, as well as various items with relatively high safety protection performance. field. Background technique [0002] Using traditional packaging materials, such as foamed plastic, EPE, paper and hard plastic, etc., it is often difficult to provide items with high safety protection performance requirements. However, air has been used as the cheapest and environmentally friendly packaging medium. When air and film are combined to form packaging materials, it has incomparable advantages in previous packaging materials, such as extrusion resistance, shock resistance, drop resistance and cushioning. Excellent comprehensive protection performance. [0003] The air-pa...

Problems solved by technology

[0003] The air-packing materials mentioned above also have traditional primitive methods, such as balloons, which are tied with strings after inflation to prevent air leakage, and a series of complex valves such as so-called stop valves, safety valves, and mechanical valves. Or plugs, etc., they have a certain one-sidedness and inconvenience in actual production and operation
