A method for forming an environmentally friendly packaging bag

Abstract

The invention relates to a method for forming and processing an environmentally friendly packaging bag, which mainly includes the following steps: material preparation, blow molding operation, bending and hot pressing, collection operation, and testing and packaging. The used packaging bag bending and hot pressing equipment includes: Bottom, stretching device, adjusting device, pressing device and hot pressing device, the present invention can solve the following difficult problems existing in the bending and hot pressing of the existing packaging bag, a, when the traditional packaging bag is bent and hot pressed, manual adjustment is required The packaging bag is bent, and the packaging bag is manually hot-pressed with a hot-pressing tool. The manual hot-pressing production of the packaging bag has low work efficiency and high cost; b, the existing packaging bag bending and hot-pressing equipment When the bag is bent, the packaging bag will not be bent evenly, and there will be wrinkles in the hot-pressed packaging bag, which will affect the appearance of the packaging bag, waste raw materials, and can improve the bending and hot-pressing efficiency and quality of the packaging bag.

Description

technical field [0001] The invention relates to the technical field of packaging product production, in particular to a method for forming an environmental protection packaging bag. Background technique [0002] Packaging bags refer to bags used to package various supplies, so that goods can be easily transported and stored in the process of production and circulation, and are widely used in daily life and industrial production. Actual figures show that 80% of plastic bags are used and eventually Just like general garbage, it is transported to the garbage dump area for disposal. Only 7% of the plastic is recycled and used. There is product structure. [0003] However, the existing packaging bags have the following problems when they are bent and hot pressed: a. When the traditional packaging bags are bent and hot pressed, it is necessary to manually bend the packaging bags, and at the same time, use a hot pressing tool to manually press the packaging bags. operation, the p...

Problems solved by technology

[0003] However, the following problems exist in the existing packaging bags when they are bent and hot-pressed, a. When the traditional packaging bags are bent and hot-pressed, it is necessary to manually bend the packaging bag, and at the same time use a hot-pressing tool to manually heat-press the packaging bag operation, the packaging bag produced by manual hot pressing has low work efficiency and high cost; b, when the existing packaging bag bending and hot pressing equipment bends the packaging bag, the packaging bag is bent unevenly, and the packaging bag after hot pressing There are wrinkles, which affect the appearance of the packaging bag and waste raw materials, which can improve the bending and heat-pressing efficiency and quality of the packaging bag
