Problems solved by technology

In this technology, both ends of the double-sided adhesive base layer are bonded by adhesive, so the demand for adhesive is relatively large in the preparation process, and there are harmful ingredients in the adhesive, which is not conducive to environmental protection.
On the other hand, the separable adhesive tape has a complex structure and a wide width. During actual use, one end will be separated and the other end will be stuck. shutdown, and the specific structure of the above-mentioned packaging film has caused its production process to be complicated, with low efficiency and high cost

Abstract

The invention relates to agricultural harvesting crop packaging materials, and particularly relates to a material formula and a production process of an automatic winding packaging film during harvesting and packaging operation of cotton, silage and the like. The material formula of the automatic winding packaging film material comprises the following raw materials in percentage by mass: linear low-density polyethylene, high-pressure low-density polyethylene, metallocene polyethylene, color masterbatch, an anti-aging agent, an ultraviolet light absorber and an antistatic agent. The productionprocess of the automatic winding packaging film mainly comprises the steps of preparing materials; blowing a film; conducting gluing; manufacturing film rolling units; and connecting the film rollingunits into a finished rolled film. By means of the material formula, the prepared packaging film is moderate in material thickness, stable in anti-aging and anti-static performance, high in anti-buffering strength, good in retraction rate and good in anti-piercing performance. The production process is reasonable in flow design, economical and practical, material bag sealing is enabled to be tightand firm, and the produced packaging film can be rapidly separated in the material packaging process.

Description

technical field [0001] The invention relates to the technical field of packaging materials for agricultural harvested crops, in particular to a material formula and a production process for wrapping automatic packaging films used for harvesting and packaging operations such as cotton and silage. Background technique [0002] Winding packaging film is used in the field of crop harvesting material packaging. Automatic packaging machinery can be used to realize automatic packaging without manual operation during use, which greatly improves packaging efficiency and economic benefits. [0003] Conventional packaging operations for cotton, silage, etc. in the prior art use roll film from a reel to pack the material, the end of the roll film must be bonded to the roll film layer below it so that it is secure Wrap the item. For example, during the working process of the cotton picker, the cotton is finally wrapped by the roll film and then packed. [0004] In the prior art, due to...
