Problems solved by technology

[0003] However, most of the current stretch films only pursue production costs, and use a lot of halogen-containing plasticizers, causing environmental pollution, and long-term use will also cause certain damage to the human body

Abstract

The invention discloses an environmentally friendly LLDPE stretch film, which is prepared from the following raw materials (by weight): 130-150 parts of LLDPE, 1-2 parts of zinc cyanurate, 17-20 partsof citric acid, 13-20 parts of n-butanol, 2-3 parts of calcium palmitate, 30-40 parts of an organic montmorillonite dispersion, 0.1- 0.2 parts of a catalyst, 0.8-1 part of monostearate monoglyceride,and 1-2 parts of zinc stearate. In the invention, the n-butanol solution of calcium palmitate is adopted to treat the LLDPE substrate so as to effectively improve thermal stability of the substrate;and then citric acid is introduced to react with the substrate under the action of the catalyst to obtain a plasticizer-modified substrate material. Through the reaction, bonding strength between thesubstrate and raw materials is improved.

Description

technical field [0001] The invention belongs to the field of films, and in particular relates to an environment-friendly LLDPE stretch film. Background technique [0002] Stretch film is mainly used for sales and transportation of various products. Its main function is to stabilize, cover and protect products. Therefore, stretch film must have high puncture resistance, good shrinkage and shrinkage stress. The initial stretch film is mainly PVC. With the continuous improvement of the performance requirements of the stretch film, the PVC stretch film is gradually reduced, and various polyethylene stretch films are developing rapidly. Polyethylene stretch film is a kind of material with good toughness, which is widely used in the whole assembly packaging of wine, cans, mineral water, various beverages, cloth and other products. Strong tear resistance, not easy to break, not afraid of moisture, large shrinkage. [0003] However, most of the current stretch films only pursue pr...
