Advantages

　　I. Thick-sheet thermoforming processing ensures project feasibility.

　　In the packaging manufacturing process, unless you use cardboard as your packaging material, no other processing method can compete with thick‑film blister‑forming technology in the market. The primary advantage of thick‑sheet thermoforming lies in its engineering efficiency. By forming composite sheets, polyurethane foam sheets, and packaging and printing sheet products, it allows for moderate tooling changes, eliminating the need to switch between thick‑plate blister‑forming equipment and molding machinery. Products with very thin walls can be processed using high‑melt‑viscosity materials, while powders of the same wall thickness are injected at low melt viscosities. For small batches of plastic parts, the favorable tooling costs represent another benefit of thick‑blister processing. For large‑volume production, this process enables extremely thin wall thicknesses, and high‑capacity thermoforming equipment is particularly advantageous.

　　II. The thermoforming process for thick sheets offers a wide range of raw material options.

　　Thermoforming can produce small components such as pill packaging or rechargeable batteries for wristwatches, and it can also fabricate very large parts, like garden water tanks measuring 3 to 5 meters in length. The thickness of the molded material can range from 0.05 to 15 mm; for foamed plastics, thicknesses up to 60 mm are achievable. Any thermosetting plastic or material with similar properties is suitable for thermoforming.

　　III. Scrap Material Procurement

　　Light cutting may leave behind residual material. After this residue is crushed, it can be blended with the original raw material and then reprocessed into flakes.

　　In recent years, the recovery of residual materials has become increasingly critical throughout the entire process of thick‑plate blister packaging. Today, waste materials are crushed and then blended with virgin eco‑friendly raw materials, enabling their recycling and reuse—a practice that has given rise to a specialized processing technology.

　　By many standards, waste plastics and rubber products—such as packaging materials and even those used in construction projects—can be recycled; however, certain aspects still require further development. At this stage, the primary acquisitions consist of chemical feedstocks and electrical energy inputs.

　　To enhance recycling rates, we must strive to make the entire processing chain more environmentally sustainable and economically viable.

　　Disadvantages

　　1. Only bet on single or double outcomes.

　　During thermoforming, only one surface of the sheet comes into contact with the mold, so only that surface conforms to the mold’s geometry. The contour of the product’s other surface is achieved through yarn splitting.

　　II. Relatively high costs

　　The raw materials commonly used in thermoforming of thick sheets are sheets with thicknesses ranging from 0.05 to 15 mm, which are semi‑finished products manufactured from powdered or granular resins. Consequently, compared with injection molding, the use of sheet‑molding materials in thermoforming entails additional costs.
