Blister packaging production process
The production process of vacuum forming packaging involves careful selection of quality raw materials and strict control of processing conditions. By using low internal stress resin modifications and incorporating small amounts of melted blends such as polyolefin, nylon, and polyester, stress resistance and water resistance can be improved. The thickness of vacuum-formed packaging varies, and it is not a case of thicker being better; rather, it should be suitable to leverage its advantages. When purchasing vacuum-formed packaging, considerations should be based on the product's appearance and quality.
In the production process, determining the thickness of the vacuum-formed packaging sheet is crucial. Starting from design, mold creation, and sampling, samples are produced based on factors like product grade and weight. The chosen thickness is then adopted to accurately determine the price. The long-term usage temperature range is 0-110 degrees Celsius. The characteristics of PP material make its thermal molding process challenging, earning it the nickname "playful PP material" in the vacuum forming industry.
The pursuit of biodegradability in vacuum-formed packaging has become a goal. The future of vacuum-formed packaging holds the promise of a better, pollution-free experience. One of its objectives is to protect products during handling, classification, and storage, reducing losses caused by constant contact.
The production of vacuum-formed packaging involves replicating the approximate shape manually after creating a physical prototype. The process includes sizing according to product dimensions, manual cutting, trimming, and edge sealing. Although the production procedure for a vacuum-formed packaging sample is intricate and entails substantial costs, its environmental adaptability, ease of recycling, and cost-effectiveness make it an ideal packaging material meeting environmental protection requirements.
Minxing's vacuum forming molds use aluminum molds with a water cooling system and base, distinguishing them from electroplated copper molds commonly used elsewhere. The advantages are evident: durability, low wear and tear, self-contained base addressing mold splicing issues, the ability to freely arrange molds based on product size, and a built-in water cooling system eliminating water marks on formed products, ensuring fast molding speed.
Moreover, the vacuum forming process employs secondary heating, ensuring uniform heating of the sheet material and stable product quality. Cold die cutting molds, instead of iron or laser knife molds, are used for trimming vacuum-formed products, resolving quality issues such as uneven surfaces and burrs caused by molds. Ready-made molds are available for cosmetic tool blister packaging, eliminating the need for customers to pay mold fees and saving costs.
