Description

High-strength blow-molded bottle blank

Technical Field

The utility model relates to the technical field of blow-molded bottle bodies, in particular to a high-strength blow-molded bottle blank.

Background

Blow molding is one method of molding thermoplastics. A method of blowing a hot parison or sheet closed in a mold into a hollow article by fluid pressure. There are both injection blow molding and extrusion blow molding. In the former, the raw materials are first formed into molten parison by an extruder or an injection machine, then the molten parison is placed in a mold, the parison is blown by compressed air to be tightly attached to the mold wall, and after cooling and demolding, hollow products such as plastic bottles, barrels, spheres and the like are obtained.

At present, most of the existing high-strength blow-molded bottle blanks have the defect of insufficient longitudinal strength, and are easy to deform under pressure when used as packaging bottles. Accordingly, there is a need for a new high strength blow molded bottle that addresses the above-mentioned deficiencies.
