Injection molds are widely used in our lives, and their applications in the packaging industry are becoming more and more prominent. Shijiazhuang Xintai Mould Factory stated that the wide application of injection moulds in the packaging industry is an advancement in hot runner technology. By adopting the thin-wall injection molding process, the cost of raw materials can be saved. Other special processes such as stamper marking method and multi-component technology have also played a positive role in reducing process steps, increasing yield and improving efficiency.

Plastic packaging materials, especially in the food industry, have made a great contribution to improving our living standards today due to their light weight and good durability. In addition, it would be unimaginable to distribute products produced by large-scale industrialization to all parts of the world without packaging materials. So on the whole, in the past few years, the entire plastic packaging market, mainly deep-drawn packaging plastic films, has grown rapidly. Among them, injection-molded packaging materials, such as packaging boxes or cups, are on the rise and gradually replace thermoformed packaging materials.

From this point of view, the following trends can be inferred:

Higher material costs and additional emission fees have prompted people to use lightweight packaging materials. The requirements for the performance of packaging materials are getting higher and higher. Today's good packaging materials should have many functions, such as good writeability, prevention of accidental opening and accurate portion distribution. Due to the globalization of packaging materials processing and sales, the output of packaging materials has increased rapidly. As a result, multi-layer cavity molds have been widely used.

This development not only has an impact on production, but also affects the product itself. Although the increase in productivity and the reduction in product weight have always been priority factors, there will still be other issues, such as consumer protection and word marking.

The requirements for comfort and consumer protection can be achieved by a corresponding safety lock. In order to increase the strength of the edge part, you can add fastening ribs. This measure can improve the overall performance of the material, if it is a thermoformed material, it is impossible to achieve this effect. In addition, polypropylene with good transparency can exert its optical properties, and printing can be omitted by stamping.
