The key to improving the quality of plastic packaging

Plastics can be seen everywhere in our daily lives. Promotional shampoo bags as small as a few millilitres are large enough for civilian passenger cars and civil passenger aircrafts to use plastics as raw materials. Plastics can be broadly divided into thermoplastic plastics and thermosetting plastics. The application of pan-environment is extremely broad. Therefore, improving the quality of plastics has always been a major issue in the industry. For more than a decade in my career, I have always attached great importance to improving the quality of plastic packaging products. Through continuous research, practice, and reading of relevant domestic and foreign materials, we have accumulated some effective knowledge and experience. We have learned profoundly that the key to improving the quality of plastic packaging products is the concept, the second is the raw material, and the third is the appliance.

Quality concept is fundamental

To improve the quality of plastic packaging products, it is essential to strengthen people's quality concept. Some well-known daily domestic companies do not hesitate to pay high prices and do not dare to go far. They must go abroad to purchase plastic packaging. The reason is that the overall performance of overseas plastic packaging products is good; especially in the design, color matching, technology level, process management, Quality assurance system and other high quality. Therefore, only by upholding the quality concept can we fundamentally improve the quality of plastic packaging products.

Raw material quality is the key

HDPE and PET are commonly used in the industry to blow plastic raw materials, but the raw material quality levels are uneven. The raw materials of the same brand with the same manufacturer are divided into several grades according to the quality level, and there are also other materials. Therefore, as a manufacturer of plastic packaging products, we must strictly control the quality of raw materials. If this key cannot be grasped, it will lose the foundation for improving product quality.
Taking a PET container as an example, raw materials with a viscosity of 0.8 or more should be used. Individual manufacturers use low-viscosity raw materials in order to reduce costs. After the finished products are liquid-filled, they fall from a height as high as one meter. There will be disruption, which will often cause the use of the company to suffer. If the manufacturer is used to understand the relevant knowledge, serious consequences can be prevented; if the experience is insufficient, once the product is on the market, it may cause major accidents of hundreds of thousands and millions of dollars. , and even led to the closure of the company!

"High quality is high price, quality is low price" This is the eternal law of the market! The use of manufacturers must focus on ensuring the quality of the product.

High quality appliances are guaranteed

With high-quality raw materials, it is not always possible to produce high-quality products, but also good manufacturing machinery and molding dies.

In addition to selecting brand-name products as far as possible, it is necessary to pay special attention to contracting the manufacturers of plastic machinery in order to ensure that their mechanical properties are in line with the “Product Performance Manual”. The use of high-viscosity plastic materials to detect the amount of plastic injection, injection pressure, plasticizing ability; if you can use PMMA, PC, PET, the performance of the equipment to achieve the "Product Performance Manual" data provided Is a good device! However, in fact, many injection molding machine manufacturers cannot guarantee that the actual function will reach the marked performance level. There are gaps in the indicators, the quality of production cannot be guaranteed, and it is even less likely to exert high efficiency.

The effect of the mold is more intuitive than that of machinery. Product quality, dimensional accuracy and finish depend on the quality of the mold. The quality of the mold depends on the use of steel, heat treatment, cold processing, etc.; if the mold itself does not have high hardness, high precision, high finish and high durability, it can not guarantee the quality and continuous production of plastic products.

Therefore, all users of the manufacturer must remember to put these three points into practice during the production process. Only in this way can the quality of plastic packaging products be put forward practically and the market competitiveness of the products can be enhanced!
