Embodiment 1

[0020] The following components are calculated by weight ratio: 70 parts of high-density polyethylene, 0.5 parts of wood flour, 1 part of dioctyl phthalate, 0.5 parts of CPE, 1.5 parts of metallocene, 4 parts of linear polyethylene and titanium 0.2 parts of white powder.

[0021] The present invention also provides a method for preparing the high-temperature liquid plastic film, which is characterized in that it comprises the following steps:

[0022] (1) Measure each component according to the formula, mix and stir, adopt back distillation method, control the temperature at 100°C, dissolve the material completely, and obtain the mixed solution;

[0023] (2) Let the mixed solution stand at 100°C for 1 hour, pour it into a flat-flow mold preheated to 100°C, and cast it onto a mirror steel plate at room temperature, so that the mixed solution is rapidly cooled and gelled, and peeled off from the steel plate to make High temperature liquid plastic film.

Embodiment 2

[0025] The following components are calculated by weight ratio: 90 parts of high-density polyethylene, 5 parts of diatomaceous earth, 10 parts of dibutyl phthalate, 5 parts of MBS, 8 parts of metallocene, 8 parts of linear polyethylene and oxidation 1 part of zinc.

[0026] The present invention also provides a method for preparing the high-temperature liquid plastic film, which is characterized in that it comprises the following steps:

[0027] (1) Measure each component according to the formula, mix and stir, adopt back distillation method, control the temperature at 150°C, dissolve the material completely, and obtain the mixed solution;

[0028] (2) Put the mixed solution at 130°C for 2 hours, pour it into a flat-flow mold preheated to 100°C, and cast it on a mirror steel plate at room temperature, so that the mixed solution is rapidly cooled and gelled, and peeled off from the steel plate to make High temperature liquid plastic film.

Embodiment 3

[0030] The following components are calculated by weight ratio: 85 parts of high-density polyethylene, 1.5 parts of asbestos, 3 parts of diisodecyl phthalate, 2 parts of ABS, 3 parts of metallocene, 5 parts of linear polyethylene and zinc barium White 0.5 parts.

[0031] The present invention also provides a method for preparing the high-temperature liquid plastic film, which is characterized in that it comprises the following steps:

[0032] (1) Measure each component according to the formula, mix and stir, adopt back distillation method, control the temperature at 120°C, dissolve the material completely, and obtain the mixed solution;

[0033] (2) Let the mixed solution stand at 125°C for 1.5 hours, pour it into a flat-flow mold preheated to 95°C, and cast it on a mirror steel plate at room temperature, so that the mixed solution is rapidly cooled and gelled, and peeled off from the steel plate to make High temperature liquid plastic film.

Abstract

The invention discloses a high-strength food packaging film which is composed of the following raw materials in parts by weight: 50-90 parts of high-density polyethylene, 0.5-5 parts of filler, 1-10 parts of plasticizer, 0.5-10 parts of modifier, 0.5-10 parts of metallocene, 3-10 parts of linear polyethylene and 0.1-2 parts of edible pigment. The high-strength food packaging film has high bearing load, and is widely used in food transfer packaging bags.

Description

technical field [0001] The invention belongs to the technical field of chemical industry, in particular to a high-strength food packaging film. Background technique [0002] The output of my country's plastic film accounts for about 20% of the total output of plastic products, and it is one of the fastest growing categories of plastic products. As the demand for plastic film in my country's packaging, agriculture and other fields is not only increasing, it is estimated that the demand for plastic film in my country will increase at a rate of more than 9% every year, and its market prospect is very broad. [0003] Among the plastic packaging materials, the market demand for film materials has increased the most, accounting for about 46% of the total plastic packaging materials. Plastic packaging films mainly include: heat shrinkable packaging film, wrapping packaging film, food aseptic packaging film, fruit and vegetable fresh-keeping film, liquid packaging film, etc. With ...
