Embodiment 1

[0029] As shown in Figure 3, the six-layer co-extrusion non-barrier sheet produced by the method of the present invention is processed by a three-layer co-extrusion blown film machine with additional hot pressing rollers.

[0030] The specific manufacturing process is as follows:

[0031] As shown in Figure 1 and Figure 3, in the existing three-layer co-extrusion blown film equipment (Figure 2), the required various resins and raw materials are weighed according to the set ratio after being weighed through the automatic metering hopper After entering the screw 1, it is heated and melted and blown out from the die head. The blown film bubble 2 is drawn by the herringbone frame 3 to form two co-extruded three-layer films with the inner layers facing each other. Afterwards, make the three-layer film that two inner layers are opposite pass through hot pressing roll 4 simultaneously, the temperature of hot pressing roll 4 is 50 ℃, guarantee good compound strength between the bondin...

Embodiment 2

[0033] As shown in Fig. 4, the fourteen-layer co-extrusion non-barrier sheet produced by the method of the present invention is processed by a seven-layer co-extrusion blown film machine with additional hot pressing rollers.

[0034] The specific manufacturing process is as follows:

[0035] As shown in Figure 1 and Figure 3, in the existing seven-layer co-extrusion blown film equipment (Figure 2), the required various resins and raw materials are weighed according to the set ratio after being weighed through the automatic metering hopper After entering the screw 1, it is heated and melted and blown out from the die head. The blown film bubble 2 is drawn by the herringbone frame 3 to form two co-extruded seven-layer films with opposite inner layers. Thereafter, the seven-layer film opposite to the two inner layers is passed through the hot pressing roller 4 at the same time, and the temperature of the hot pressing roller 4 is 80° C. to ensure good composite strength between th...

Embodiment 3

[0037] The 26-layer co-extrusion barrier-free sheet produced by the method of the present invention is processed by a 13-layer co-extrusion film blowing machine with additional hot pressing rollers.

[0038] The specific manufacturing process is as follows:

[0039] As shown in Figures 1 and 3, in the existing thirteen-layer co-extrusion blown film equipment (as shown in Figure 2), the required various resins and raw materials are weighed through the automatic metering hopper and then weighed according to the set formula. The ratio enters the screw 1, and after being heated and melted, it is blown out from the die head, and the blown film bubble 2 is drawn by the herringbone frame 3 to form two co-extruded thirteen-layer films with the inner layers facing each other. Thereafter, two thirteen-layer films with opposite inner layers are passed through the hot pressing roller 4 at the same time, and the temperature of the hot pressing roller 4 is 100° C. to ensure good composite s...

Abstract

The present invention discloses process and apparatus for producing packing plastic material. The process includes the following steps: feeding material through several feed ports including feeding adhesive resin material in the inner layer feed port, melting and blowing to produce film bubble, cooling, drawing to form two sheets of film, hot pressing, and cutting and winding. Compared with available technology, the present invention has the advantages of low production cost, simple produce process, high material homogeneity, high compounding strength and rich colors.

Description

technical field [0001] The invention relates to a production process and equipment for packaging materials, in particular to a production process and equipment for all-plastic packaging materials. Background technique [0002] At present, there are two main processes for making plastic hose packaging films: one is the extruded hose commonly used in cosmetic packaging, and the extruded tube is obtained at one time through extrusion equipment; the other is used in toothpaste packaging and some pharmaceuticals The co-extruded aluminum-plastic or plastic-plastic composite film with more than five layers on the package is mainly composed of multi-layer plastic film or composited with aluminum foil. Due to one-time molding, the resin used in the former is polyethylene or polypropylene, and the resulting pipe has no barrier properties, and the extrusion process is relatively complicated. The extruded pipe has disadvantages such as poor thickness uniformity and high processing costs...
