The production process of blister heat seal packaging color card is a complex and delicate process, which combines multiple links such as blister molding, heat sealing and color card printing.
The first step in producing blister heat seal packaging color card is to prepare raw materials, which mainly include plastic sheets (such as PVC, PET, PS, etc.) and color card paper. The plastic sheet needs to have sufficient flexibility and plasticity so that it can be smoothly adsorbed on the mold after heating. The color card paper is used to print product information, brand logo, etc. After the raw materials are prepared, the plastic sheet needs to be pre-treated, such as dust removal and dehumidification, to ensure that its surface is clean and flat, and avoid blistering, deformation and other problems in subsequent processing.
The mold is a key tool for blister molding, and its design directly affects the shape, size and precision of the product. In the mold design stage, the shape, size and material of the mold need to be determined according to the specific needs of the customer and the characteristics of the product. When making the mold, materials such as plaster molds, copper molds or aluminum molds are usually used, which have good processing performance and durability. After the mold is made, it is also necessary to inspect and debug it to ensure that it can meet the production requirements.
Blister forming is the core link of producing blister heat seal packaging color card. In this step, the pre-treated plastic sheet is first fed into the blister machine and softened by heating. Then, the softened sheet is adsorbed on the mold and tightly fits the mold surface by vacuum or air pressure. After the sheet is cooled and shaped, the molded product can be removed from the mold. During the blister forming process, parameters such as heating temperature, time and vacuum degree need to be strictly controlled to ensure the quality and stability of the product.
While blister forming, the color card needs to be printed and cut. Color card printing usually uses advanced printing equipment and technology, such as offset printing and gravure printing, to ensure the high clarity of printing quality and the vividness of color. After printing, the color card needs to be cut according to the size and shape of the product to match the blister product.
Heat sealing is the key step to firmly bond the blister product to the color card. In this step, a heat sealer is usually used to heat and pressurize the edge of the color card coated with heat seal glue and the blister product to make them tightly combined. During the heat sealing process, parameters such as temperature, pressure and time need to be strictly controlled to ensure the firmness and beauty of the heat sealing effect. After the heat sealing is completed, the blister product and the color card need to be assembled to form a complete packaging product.
During the production process, quality inspection is required for each link to ensure the quality and stability of the product. This includes the inspection of the dimensional accuracy, surface quality, heat sealing effect and other aspects of the blister finished product. After passing the inspection, the finished product needs to be packaged, such as boxing, labeling, etc., for transportation and storage.
The last step is the outbound and delivery of the finished product. Before leaving the warehouse, the finished product needs to be checked for quantity and appearance to ensure that it is intact. Then, according to the customer's order requirements and transportation methods, the finished product is packaged, boxed and arranged for delivery. Before delivery, relevant shipping documents and records need to be filled in to track and inquire about the transportation of the goods.
The production process of blister heat seal packaging color card includes raw material preparation and pretreatment, mold design and production, blister molding, color card printing and cutting, heat sealing and assembly, quality inspection and packaging, and finished product outbound and delivery. Each link requires strict control of quality and process parameters to ensure the quality and stability of the final product.
