Embodiment 1

[0092] The manufacturing process of the environment-friendly degradable bubble packaging bag comprises the following steps:

[0093] a. Outsourcing: buy the existing film on the market as the mask layer; 86% polyethylene, 4% flame retardant, 3% plasticizer and 7% biodegradable additive;

[0094]b. Ingredients: put 87% polyethylene, 5% plasticizer and 8% biodegradable additive into the mixer according to mass percentage, and stir for 50min to obtain mixture 1; mix 83% polyethylene, 5% antistatic agent , 6% of the plasticizer and 6% of the biodegradable additive were put into the mixer, and stirred for 40 minutes to obtain the mixture 2;

[0095] c. Forming: Extrude and form mixture 1 through the processing system, the forming temperature is 180°C, so that it forms a bubble film layer on the mask layer; then extrude and form mixture 2 through the processing system, the forming temperature is 173 ℃, so that it forms a coating layer on the bubble film layer to make a composite fi...

Embodiment 2

[0099] The manufacturing process of the environment-friendly degradable bubble packaging bag comprises the following steps:

[0100] a. Outsourcing: buy the existing film on the market as the mask layer; 86% polyethylene, 4% flame retardant, 3% plasticizer and 7% biodegradable additive;

[0101] b. Ingredients: put 90% polyethylene, 4% plasticizer and 6% biodegradable additive into the mixer according to mass percentage, and stir for 45 minutes to obtain mixture 1; mix 85% polyethylene and 3% antistatic agent , 6% of the plasticizer and 6% of the biodegradable additive were put into the mixer, and stirred for 35 minutes to obtain the mixture 2;

[0102] c. Molding: Extrude and shape the mixture 1 through the processing system. The molding temperature is 178°C to form a bubble film layer on the mask layer; then extrude the mixture 2 through the processing system and shape it. The molding temperature is 168°C. ℃, so that it forms a coating layer on the bubble film layer to make...

Embodiment 3

[0106] The manufacturing process of the environment-friendly degradable bubble packaging bag comprises the following steps:

[0107] a. Outsourcing: buy the existing film on the market as the mask layer; 86% polyethylene, 4% flame retardant, 3% plasticizer and 7% biodegradable additive;

Abstract

The invention provides an environment-friendly degradable bubble packaging bag and a manufacturing process thereof. The technical problems that an existing packaging bag is too complex in structure, capable of meeting simple use requirements, poor in using effect and the like are solved. The environment-friendly degradable bubble packaging bag comprises an inner bag body, a middle bag body and anouter bag body, wherein the inner layer bag body is a shower film layer, the middle layer bag body is a bubble film layer, the outer bag body is a mask layer, and the outer layer bag body comprises, by weight, 80-90% of polyethylene, 1-5% of flame retardants, 2.5-6.5% of plasticizers and 5-10% of biodegradable additives; the middle layer bag body comprises, by weight, 82-92% of plasticizers, 3-9%of plasticizers and 5-10% of biodegradable additives; and the inner layer bag comprises, by weight, 75-85% of polyethylene, 3-9% of antistatic agents, 5-8% of plasticizers, 5-8% of biodegradable additives, and 5-10% of degradant additives. The environment-friendly degradable bubble packaging bag has the advantage of being good in using effect.

Description

technical field [0001] The invention relates to an environment-friendly degradable bubble packaging bag and a manufacturing process thereof. Background technique [0002] The bubble bag is mainly made of polyethylene bubble film through film cutting, cutting the bubble film into the size required for bag making, and then processing it through the bubble film bag making machine. It is a kind of transparent flexible packaging material that is widely used at present. It is mainly used in the logistics and transportation protection of electronic product buffer packaging, plastic products, metal products, ceramic products, glass products and other products that require buffer protection. [0003] After searching, for example, Chinese patent literature discloses a degradable material packaging bag [application number: 201720832866.8; publication number: CN 207497223U]. This degradable material packaging bag is characterized in that it includes a hard side, a packaging bag top sur...
