How to make a lunch box product

               Plastic products are a necessity in daily life.

 Whether they are daily consumer goods or industrial products, there are many different production methods. The following are all the production

                            according to customer requirements - pack into master carton with customer printing shipping marks.


                      About 80% of plastic products in daily life are injection molding. Injection molding is the use of aluminum molds or steel molds to make products in injection molding machines. The mold consists of a core and a cavity. The injection molding machine heats the resin raw material until it melts, and uses pressure to inject the molten plastic material into the cavity of the mold, then the core and cavity are separated, and the product is ejected from the mold.            

The advantages of injection molding lie in the large quantity, high speed, low cost, wide variety, and automation.


                          There are many printing methods: silk screen printing, heat transfer printing, laser printing, pad printing, gravure printing... Our products generally use silk screen printing and heat transfer printing Heat transfer printing workmanship contains two fields: make transfer film and do transfer printing on products. The transfer film printing adopts dot printing, and the pattern is pre-printed on the surface of the film. The printed pattern layers are rich, colors are bright, colors different is small, which can meet the requirements of customer pattern design and is suitable for mass production.

                       The transfer printing through heating and pressurizing by a heat transfer machine transfers the exquisite pattern on the transfer film and transfer to the surface of the product. After molding, the ink layer is integrated with the surface of the product, which is realistic and beautiful, and greatly improves the grade of the product.
