Blow-molded packaging can be differentiated based on the product's appearance features, mainly including four categories: blow-molded boxes, trays, blister packs, and covers. Due to their varying shapes, their functions also differ. However, they share a common value: enhancing the grade and value of the products.
Next, we will provide introductions:
Blow Molding Packaging Pallets
Trays are packaging products with flat recesses. Blow-molded trays typically serve as outer packaging, with the tray packaging's effect being to load and protect items during transportation. Additionally, such packaging is stackable, mainly used for electronic components, food, fruits, and other items.
2. Blister Packaging
Blow-molded blister packaging is a unique type of packaging product with a protruding, three-dimensional appearance, mimicking the contours of the item it encases. Primarily used for toys, stationery, electronics, and more, the main advantage of blister packaging is its ability to highlight the unique features of the product.
3. Vacuum-formed Packaging Hood
Blow-molded packaging covers, also known as vacuum covers, are commonly made of transparent materials, with items placed inside. This type of packaging not only protects the product but also highlights its quality. Due to the transparency, the contents can be viewed from all 360 degrees. It is primarily used for cosmetics, electronics, toys, and more.
4. Vacuum Formed Packaging Boxes
Blow-molded packaging boxes are primarily flat with recessed grooves and a central hollow, mostly in square or rectangular shapes. These boxes are predominantly used for internal packaging, primarily serving a protective function. They are mainly applied to digital products or accessories.
Common Raw Materials:
The raw materials for vacuum-formed packaging boxes mainly include PVC, PS, PP, PET, PETG, as well as materials like velvet, antistatic, and conductive ones.
Specific production process:
Mold manufacturing and processing.
2. After the mold treatment is completely dried, it undergoes softening processing.
3. Place the softened plastic sheets along with the wooden cabinet into a vacuum chamber, activate the suction switch to remove the air inside the chamber, and then cool the plastic sheets. Upon cooling, you will obtain packaging or a process mold with the same concave shape as the mold.
4. Blister Packaging Organization. Shanghai Minxing Plastic Packaging Co., Ltd. specializes in the production and customization of blister boxes.
Blow Molding Molds
Blow molding molds typically include gypsum molds, electroplated copper molds, and aluminum molds.
Gypsum Molding
Gypsum molds are crafted by sculpting in a semi-wet state and then dried to form. They are cost-effective and easy to modify, but lack precision, have a rough surface, and are fragile and not durable. Therefore, they are commonly used for dummy products, as substrates for electroplating copper molds, or for small-scale production of vacuum forming molds with lower requirements.
Electroplated Copper Molds
After creating samples from gypsum molds, electroplating a copper shell results in electroplated copper molds. While they are more expensive than gypsum molds, they are significantly cheaper than aluminum molds. Thanks to their smooth, durable surfaces and cost-effectiveness, electroplated copper molds are a commonly used type of vacuum forming mold.
Aluminum Molding
The aluminum molds are precision-machined from ingots using machinery (lathes, milling machines, CNC, etc.). They offer high accuracy, smooth surfaces, and durability, though they are quite expensive. Aluminum molds are typically used for vacuum-formed products that require high precision, which copper molds cannot achieve.
