Embodiment 1

[0016] A food plastic woven bag is made up of the following raw materials in parts by weight:

[0017]

[0018] The length of the glass fiber is 6mm.

[0019] Preparation method: Taking the preparation of a food plastic woven bag as an example, the preparation method of a food plastic woven bag provided in this embodiment is described as follows:

[0020] First, polypropylene, glass fiber, diethyl phthalate, wood powder, nano-sized montmorillonite, maleic anhydride grafted polypropylene, antioxidant 1010, green tea powder and barley oil are fed into a high-speed mixer for heating and melting Mix evenly at a speed of 1000 rpm; then add the above mixture to a twin-screw extruder at a speed of 500 rpm and extrude for 15 minutes. Cloth can get food plastic woven bags.

Embodiment 2

[0022] A food plastic woven bag is made up of the following raw materials in parts by weight:

[0023]

[0024] The length of the glass fiber is 20mm.

[0025] Preparation method: Taking the preparation of a food plastic woven bag as an example, the preparation method of a food plastic woven bag provided in this embodiment is described as follows:

[0026] First, polypropylene, glass fiber, dipentyl phthalate, wood flour, wollastonite, maleic anhydride grafted polypropylene, antioxidant 1010, green tea powder and barley oil are fed into a high-speed mixer for heating, melting and mixing , the rotating speed is 1500 rpm; then the mixture is added to the twin-screw extruder with a rotating speed of 800 rpm and extruded for 10 minutes. Food plastic woven bags are available.

Abstract

The invention discloses a plastic woven food bag and a preparation method thereof. The plastic woven food bag comprises the following components in parts by weight: 100 parts of polypropylene, 0.1-0.8 part of glass fiber, 2-10 parts of a plasticizer, 20-40 parts of wood meal, 15-30 parts of a nano material, 2-6 parts of a compatilizer and 1-4 parts of aids. The preparation method comprises the following steps: firstly, putting the components into a high-speed mixer for heating, melting and mixing uniformly; putting the obtained mixture into a twin-screw extruder for extruding for 10-15 minutes, and performing discharging, cooling, coiling and cloth weaving on the extruded material, , thereby obtaining the plastic woven food bag. The toughness of the plastic woven food bag disclosed by the invention is improved to a certain degree; due to the addition of an antioxidant 1010 and the glass fiber, the service life of the plastic woven food bag is prolonged; and due to the addition of non-toxic and harmless green tea powder, barley oil and the like, a threat of the added harmful components to food safety is avoided.

Description

technical field [0001] The invention relates to the technical field of plastic woven bags, in particular to a food plastic woven bag and a preparation method thereof. Background technique [0002] Plastic woven bags have the advantages of light weight, high strength, and acid and alkali corrosion resistance, so they can get good application results in the field of food packaging. Currently commonly used food plastic woven bags have the disadvantages of low toughness and easy damage during processing and storage, resulting in low service life of food plastic woven bags. In addition, the addition of harmful substances during the processing of food plastic woven bags will Food safety poses a threat and directly affects the quality of food in plastic woven bags. Contents of the invention [0003] The invention aims to solve the deficiencies of the prior art, and provides a food plastic woven bag and a preparation method thereof. [0004] In order to achieve the above object,...
