Problems solved by technology

[0004] Therefore, the cost of film blowing equipment with more than five layers is high, the film is unstable, the film is thicker (above 3.6C), and the film mechanical properties and barrier properties of two-layer and three-layer blown film equipment are poor, and the pressure-bearing performance of the bubble bag is poor. Problems such as protecting products during long-term transportation need to be solved urgently

Embodiment 1

[0074] A raw material for the manufacture of thin films, the composition of which is as follows.

[0075] According to parts by weight, the first group of materials is composed of 40-60 parts of high-density polyethylene, 30-40 parts of linear low-density polyethylene, and 10-15 parts of polyolefin elastomer. The elastomer is a polyolefin elastomer. The second group material is composed of 60-70 parts of high-density polyethylene, 8-15 parts of polyamide, 10-15 parts of metallocene polyethylene and 5-20 parts of compatibilizer in parts by weight. The compatibilizer is high-density polyethylene with a maleic anhydride graft rate of 2% and a melt index of 1 g / min. According to parts by weight, the third group of materials is composed of 50-70 parts of linear low-density polyethylene, 30-50 parts of metallocene polyethylene, and 0.5-1 part of antiblocking agent. The blocking agent is silicon dioxide.

Embodiment 8

[0085] The raw materials provided in Example 1 were used to prepare a three-layer co-extrusion film through a PE co-extrusion blown film machine. The outer layer of the co-extrusion blown film machine sets the plasticizing temperature of the screw at 180°C and the film head temperature at 175°C; the middle layer sets the plasticizing temperature of the screw at 185°C and the temperature of the film head at 180°C; the inner layer sets the plasticizing temperature of the screw at 140°C. The membrane head temperature is 135°C. The thickness of the prepared co-extruded film is 1.5C.

[0086] Examples 9-14 correspond to the raw materials of Examples 2-7 to prepare a three-layer co-extruded film according to the process flow of Example 8. The conditions are shown in Table 3, and the corresponding film properties are shown in Table 4.

Abstract

The invention discloses a raw material for preparing a thin film, a bag product, a packaging thin film and a preparation method thereof, and belongs to the field of packaging. The raw material comprises a first composite material, a second composite material and a third composite material which are independently provided respectively. The raw material mainly comprises polyethylene, nylon and an elastomer. The thin film product prepared by using the raw material provided by the invention, particularly a co-extruding thin film, can achieve an excellent mechanical property.

Description

technical field [0001] The invention relates to the field of packaging, in particular to a raw material for preparing a film, a bag product, a packaging film and a preparation method thereof. Background technique [0002] In recent years, with the rise of cushioning air cushion equipment, a large number of film products based on high-density polyethylene (HDPE), low-density polyethylene (LDPE) and low-density polyethylene / nylon (LDPE / PA) have flooded into the cushioning protection market . [0003] At present, two-layer and three-layer blown film equipment suitable for PE and five-layer and seven-layer blown film equipment suitable for PA or EVOH are generally used to prepare film products for cushioning packaging. However, due to the poor plasticizing effect of the screw, the PE type two-layer and three-layer blown film machine is limited to PE plastic rice, and the mechanical properties, cushioning protection performance and barrier performance of the prepared film are po...
