Plastic Packaging Containers Oct 25, 2018

In general, the molding method is used, and its morphology is mainly determined by the forming methods and the moulds used. Sometimes the same (or similar) patterns can also be made in different ways. For example, hollow containers are generally used in blow molding method, but also often used in rotational molding method manufacturing (especially large containers, small batches of containers or special-shaped containers); Turnover box is generally used injection molding method, but in some of the more special cases, in order to adapt to the use of the need to adopt calcium-plastic plate manufacturing (with light,The advantages of low price, but less strength) or by the pre-foamed polystyrene bead Molding (with special outstanding thermal insulation properties and good cushioning shock resistance), even using sheet thermoforming method Manufacturing (low cost but limited strength). Molding method is different, often the product performance, cost has a great impact, so in the selection of plastic packaging containers, if the various molding methods have a rough understanding, is quite advantageous. Plastic packaging containers commonly used in a variety of plastic properties, for the correct selection of plastic packaging containers is very important, because the plastic packaging container material, determines the basic characteristics of plastic packaging containers. Plastic packaging containers with the same or similar morphology may have very large differences in their performance due to different materials. For example, polycarbonate blow molding bottles and ordinary polyester stretch blow molding bottles, all have extremely good transparency and gloss, is very similar in appearance, but the high temperature performance of polycarbonate bottle is outstanding (can withstand 120 ℃ above the high temperature disinfection), but the barrier performance is poor, and ordinary polyester stretch blow molding bottle barrier performance is good, However, the heat resistance is poor (generally recommended to use at temperatures below 60 ℃).
