The development trend of light weight of daily chemical packaging bag plastic packaging
Reducing the weight of packaging is beneficial to both the environment and the profits of enterprises. Lightweight is a commonly used industrial term at present, which is used to describe the practice of reducing the weight of packaging by using less materials to produce packaging. Generally speaking, containers such as plastic bottles, plastic cans, plastic hoses and plastic caps are easier to achieve the goal of weight loss.
When a plastic package is successfully lightweight, less resin materials are needed in the process of injection molding. Due to the use of less packaging materials, lightweight daily chemical packaging bags are very beneficial to environmental protection, but this is not the only advantage. Lightweight packaging also has the advantages of using more, such as effectively reducing the cost of materials.
Many plastic container suppliers said that a large number of daily chemical enterprises have shown great concern for lightweight, especially for mass personal care products, such as skin care products packaged in plastic bottles or cans. Generally, plastic bottles or cans are easier to achieve lightweight goals than injection molded containers.
Lightweight plastic packaging can ease people's concerns about environmental protection and sustainable development. More and more people choose products with better packaging, faster production speed of daily chemical packaging bags, strong packaging itself and reduced weight. When Japanese chemical enterprises sell products in large quantities, a small reduction in the amount of resin in each package can bring considerable economic benefits to enterprises, especially trees Under the premise of the unprecedented increase in the price of fat raw materials, more and more enterprises are more and more interested in lightweight packaging.
In order to reduce the amount of resin used in the plastic bottle or cap, the injection molding process needs to be changed, and the continuous injection molding technology with material should be selected to replace the buckle withdrawal injection technology. The injection molding process of container bottle cap is completed. The material belt in the mold center is stripped off and the screw thread of the bottle cap is changed. In this way, the weight of the cap can be reduced and the goal of lightweight can be realized.
Expand knowledge: LDPE has poor mechanical strength, gas barrier and oil resistance, but its moisture resistance, cold resistance, chemical stability, elongation and impact resistance are good. Since LDPE is a non-polar material, its surface tension is poor, corona treatment must be carried out before printing, and its softness is good and its ductility is also large. In order to ensure the accuracy of printing overprint, it is better to use a large roller type printing machine, and pay attention to the control of tension to prevent edge swing; in order to prevent ink adhesion, the film should be cooled to below 35 ℃ during winding up. www.dgbpk.com/
