Embodiment Construction

[0023] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0024] Embodiments of the invention include:

[0025] Described double-layer plastic bag processing technology comprises the steps:

[0026] Step 1: Select raw materials for plastic products. The raw materials are: polyethylene, polypropylene, barium sulfate, dispersant, reinforcing agent, and modifier. According to the weight ratio, the polyethylene accounts for 35%-55%, 35%-40% polypropylene, 1%-5% dispersant, 1%-5% reinforcing agent, 1%-3% modifier.

[0027] Step 2: Add antioxidants and UV absorbers to the raw materials in Step 1.

[0028] The third step: in the compound in the second step, add reinforcing agent, wherein reinforcing agent is in order to improve the strength and rigidity of ...

Abstract

The invention discloses a processing method of double-layered plastic bags. The method comprises the following steps: selecting plastic products as raw materials, adding an antioxidant and an ultraviolet absorbent, adding a reinforcing agent, adding a paraffin lubricant, uniformly stirring the raw materials, selecting a blow molding machine, thermally molding, blowing film, blowing mould, shaping and cooling, flatly pressing blow mould products by using an extender, cutting the blow mould products after flatly pressing, cutting for a second time, selecting a colorful printer, cutting the film, producing bags and packing. Through the processing method of the double-layered plastic bags, the rigidity of plastic tapes is improved, so that the plastic tapes can bear high gravity; the processing method is simple; the waste of the disposable plastic products is avoided; the environment is protected.

Description

technical field [0001] The invention relates to the field of plastic products, in particular to a double-layer plastic bag processing technology. Background technique [0002] Plastic products, especially plastic bags are the most common products. The existing plastic packaging products are simple and easy, but plastic products are difficult to degrade and easily cause white pollution on the earth. Plastic products are easy to process and have a large demand. Most of them are disposable products. Throw it away after finishing, which seriously pollutes the environment, and the tensile strength of disposable products is low. Therefore, the invention provides a double-layer plastic bag processing technology, which can be used for a long time, avoiding the discarding of plastic bags, and protecting It protects the environment and saves energy. Moreover, the function of the double-layer plastic bag is the same as that of the usual cloth product bag, and the cost is low. It can al...
