Thanks to their unique process characteristics, the blister series is widely used in packaging, home decoration, industrial accessories, and other fields, but they also have obvious performance shortcomings. Below is a comprehensive summary of their core advantages and disadvantages:
✅ Core advantages
Outstanding cost and mass production advantages: mold manufacturing costs are far lower than injection molding, small batch sample thresholds are low, prototyping cycles are short, and product needs for rapid iteration are well suited; The sheet material utilization rate is high, with the overall mass production cost of only 30%-50% of injection molded parts of the same specification, offering excellent cost performance.
Standardized and regular, adaptable to automation: The product slots have high dimensional accuracy and strong batch consistency, with fully uniform placement and flatness, perfectly integrating with automated assembly line picking and packing operations, greatly improving production flow efficiency.
Excellent cleanliness and displayability: smooth surface without pores, resistant to chip shedding, excellent dust and contamination resistance, meeting the cleanliness requirements of precision electronic components; Transparent materials offer strong visualization, intuitively displaying the internal product status and enhancing the quality of terminal shipments.
Flexible adaptation to shapes and materials: Capable of creating complex three-dimensional shapes with a wide range of colors and textures. Some categories are integrated with four sides forming without the need for edge banding, completely solving issues of board edge sealing delamination and water seepage, suitable for various home styles such as European and pastoral styles.
Meets environmental protection and safety standards: Mainstream food-grade blister materials such as PP and PET are non-toxic and odorless, meeting FDA and food contact standards. They can be directly used for fresh food and microwave-heated food packaging, with most materials supporting recycling and reuse.
Wide temperature adaptation range: Modified PP vacucle can be stably used within the -40°C~120°C range, suitable for cold chain freezing scenarios as well as microwave heating needs, with excellent weather resistance.
❌ Obvious shortcomings
Poor shock absorption and cushioning ability: The material is relatively hard and almost non-elastic, completely lacking the cushioning effect of foam products. During long-distance logistics bumps, the internal products are prone to friction and collision with the hard vacuum-forming tank, causing scratches and edge wear.
Weak compression and impact resistance: When stacking multiple layers under excessive pressure, they are prone to deformation and cracking, losing their original shaping and limiting function, which leads to internal product loosening and misalignment; Some ordinary materials become brittle in low temperatures and can break directly from minor bumps.
Limited resistance to extreme environments: It cannot withstand long-term direct ultraviolet light exposure, and prolonged outdoor exposure can cause yellowing and aging; It is not resistant to strong alkalis, oxidizing acids, or ketone solvents, and is prone to dissolution and cracking upon contact with certain chemicals.
High temperature resistance has an upper limit: Ordinary PVC blister products cannot come into prolonged contact with high-temperature objects, and the PVC film on the surface is easily burned or even peeled off by cigarette butts and high-temperature kitchenware. Their fire resistance is poor, making them unsuitable for high-temperature open flame scenarios.
Significant thickness and structural limitations: Conventional blister products can only be made into thin-walled parts, which are difficult to form and have poor precision, making it impossible to produce high-strength industrial structural parts with overly complex structures and uneven wall thickness, thus limiting application scenarios.
