In the modern packaging industry, blister paper plays a vital role and is a material with many excellent properties.
Blister paper is usually a packaging form in which irregular objects are sealed and protected by using PVC or PET blister shells, and then the blister shells are glued together with paper cards. It combines the advantages of plastic and paper and exhibits many unique characteristics.
From the performance point of view, blister paper has good transparency, which allows consumers to clearly see the appearance of the product, greatly enhancing the attractiveness of the product; it has good toughness and impact resistance, which can effectively protect the product from damage during transportation and storage; at the same time, its excellent sealing can prevent the penetration of oxygen, moisture, etc., and extend the shelf life of the product.
Blister paper has a wide range of applications. In the food industry, it can be used to package small foods such as potato chips and biscuits, which is both beautiful and can protect food quality; in the medical field, it provides sealing protection for drugs to ensure the effectiveness and safety of drugs; in the electronic and electrical industry, it can prevent electronic components from being affected by the external environment; in the cosmetics industry, it creates a high-end and atmospheric display effect for products and enhances the brand image.
During the production process, the production of blister paper includes multiple steps such as material selection, mold design, heating, suction, cooling, cutting, and edge sealing. When selecting materials, plastic sheets such as polypropylene (PP) and polystyrene (PS) are often used. These sheets are easy to form and have good physical and chemical properties. There are many factors that affect the quality of blister paper, such as material properties, mold design, processing temperature and time, suction time and pressure.
However, blister paper also has some limitations, such as easy aging and deterioration due to environmental factors, and the production requires professional equipment and certain technology, which increases the production cost to a certain extent. But overall, blister paper occupies an important position in the packaging industry with its advantages, and with the development of technology, its application prospects are very broad.
