Problems solved by technology

The raw material film of the adhesive bag, usually PE film, has the characteristics of easy stretching and deformation under heat and force. The added adhesive will stretch to a certain extent on the adhesive bag, and there is a possibility of glue overflowing during slitting after coating. Phenomenon, after the existing hot-melt adhesive is coated with PE film, the die-cutting is easy to break, and the colloid does not rebound, but little attention is paid to the impact of this aspect. The hot-melt adhesive of the prior art still does not have anti-wrinkle adhesive performance

Abstract

The invention discloses an anti-wrinkle environment-friendly hot-melt adhesive for film adhesive bags, which is prepared according to parts by weight, and comprises the following raw material components: 25-35 parts of solution polystyrene butadiene, 12-20 parts of plasticizer DINCH, 40 parts ‑55 parts of styrene-modified C5 resin, 3‑8 parts of low molecular weight polyisobutylene, 1‑3 parts of PE wax and 1‑1.5 parts of antioxidant, using solution polystyrene butadiene system, with good die-cutting performance and low shrinkage With DINCH as the plasticizer, the viscosity and tensile strength of the polymer can be significantly reduced, and the plasticizer DINCH and polyisobutylene can synergistically reduce the internal stress of the colloid, so as to achieve anti-wrinkle for the label applied to the film type adhesive bag after coating The effect, and has excellent die-cutting performance. The present invention also proposes a method for preparing the wrinkle-resistant environmentally friendly hot-melt adhesive for film adhesive bags, and a method for preparing film adhesive bags using the wrinkle-resistant environmentally friendly hot-melt adhesive for film adhesive bags, The process is simple and easy to operate.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a wrinkle-resistant and environment-friendly hot-melt adhesive for film adhesive bags, a preparation method and application thereof. Background technique [0002] With the development of the economy and the improvement of people's living standards, the express logistics industry has also achieved rapid development. Hot melt adhesives are safe and environmentally friendly, especially suitable for high-speed production, and are widely used in the logistics and packaging industry. Film-back plastic bag is one of the common carriers of logistics waybills. It is used for the transportation of product transportation transfer bills, bills of lading, invoices or safety data. It has self-adhesive adhesive on the back and can be pasted on any surface, which is easy to use. The raw material film of the adhesive bag, usually PE film, has the characteristics of easy stretching an...
