    The Benefits of Blister Packaging for Shipping Wide variety Blister packaging comes in a wide variety of shapes, sizes and strengths. The different variations mean you can choose the packaging solution that best protects your products based on how you intend to transport them.  Keeps items fresh  For long-haul shipping, blister packaging can protect perishables from air and moisture exposure, minimizing deterioration. Foods and medications are protected from environmental factor-induced spoilage when packaged in blister packs.  Blister packaging is usually water-resistant, and it protects against ultraviolet (UV) light and any impacts so your products remain fresh and undamaged throughout the duration of the journey.  Security Shipping medications raises concerns that the product could be tampered with. Blister packaging makes it difficult for a non-intended recipient to access the product, and it’s easy to tell when blister packs have already been opened, making them safe vehicles for transporting medications. Cost-effective Blister packaging can reduce shipping costs because it reduces the need for additional packaging. Plus, they can be customized in a variety of ways to fit any product, which makes items easier to store in cardboard boxes for bulk shipping. Eco-friendly packaging Most blister packs are made for reuse and, in some cases, can be recycled, making them eco-friendly packaging solutions.  FDA approved Blister packs can be easily customized to meet FDA considerations for container labels for shipping medications. The SUPPORT Act allowed the FDA to require special packaging, such as blister packs, to ship opioids and other types of medication that pose a risk of abuse or overdose. Combining Cardboard Cartons and Blister Packs for Better Shipping While blister packaging offers many protective properties for shipping items, this packaging solution tends to be irregularly shaped. Storing blister packs inside cardboard boxes makes stacking and shipping items easier, especially when they’re being transported in bulk.  Using cardboard adheres to current standards regulating what eco-friendly packaging materials are, and corrugated boxes provide blister packed items an additional layer of protection, making the dual system ideal for long-haul transportation. The combination of blister packaging and cardboard containers helps to keep shipping costs down. Customizing your cardboard box so that it’s made to measure will reduce costs further. Many shipping firms charge based on box dimensions, so reducing box dimensions means a lower cost to transport goods. Choose Air Sea Containers for Your Custom Cardboard Boxes Air Sea Containers uses recyclable materials for all your packaging needs. Our Hazmat-approved and non-Hazmat custom corrugated boxes are the ideal solution for shipping irregularly shaped, blister packed items anywhere in the world. For all your packaging needs and to ship items...
  • Replacing plastic with bamboo, adding bamboo to the vacuum forming industry chain
    Replacing plastic with bamboo, adding bamboo to the vacuum forming industry chain
    March 31, 2026
    In the global wave of plastic pollution control, bamboo, a rapidly growing and biodegradable natural material, is entering the field of vacuum formed products with its unique physical properties and environmental advantages, becoming a part of replacing traditional plastics. They are mostly made by blending bamboo fiber/bamboo powder with fully biodegradable materials such as PLA and RPET, and then forming them into sheets through vacuum forming/molding processes. They are widely used in scenarios such as food delivery, food packaging, and logistics lining. There is currently no authoritative national unified statistical data on the market share of bamboo vacuum formed products in the food and beverage delivery field, and its approximate position can only be understood from the current industry situation and local data. Overall market share: Still a niche market, but growing rapidly. Market size: In 2024, the sales volume of disposable lunch boxes in China is about 84.9 billion, with plastic lunch boxes still dominating. Bamboo products positioning: Bamboo fiber lunch boxes, tableware, etc. belong to "environmentally friendly alternatives". According to monitoring by the Ministry of Commerce, the usage of such substitutes increased by 26.31% month on month in the first half of 2025, indicating that they are in a period of rapid penetration, but the base is still small, in the single digits, and far from becoming mainstream in the market. After purchasing fresh bamboo leaves and bamboo slices for the production project of "replacing plastic with bamboo", they are subjected to coarse crushing, ultrafine crushing, graded screening, and drying to obtain ultrafine powder with a mesh size of 500-5000. Some ultrafine powders are sold as products, some are mixed with PLA and PBAT for granulation to obtain biodegradable particles A, some are mixed with PLA for granulation to obtain biodegradable particles B, and some are mixed with PLA and PBAT for injection molding into packaging boxes. Part of the biodegradable particles are sold as products, and some of the biodegradable particles A are blown to obtain biodegradable plastic film. After blowing and bag making, biodegradable express bags are obtained, and biodegradable lunch boxes are obtained through vacuum forming; Partially biodegradable particles B are injected into biodegradable cups, bowls, knives, forks, and spoons.

    What Is Blister Packaging and Why Is It Used?
    July 13, 2023
    Consumers are likely unfamiliar with the term “blister packaging,” but it is used in a wide range of products and industries. Heavily adopted by the pharmaceutical industry in the 1960s, blister packaging is a classic choice for tablets and capsules. In that industry, blister packs are favored for their durability, dose management, and tamper-proof construction. These qualities have made it valuable in many other sectors including commercial cannabis and vape products. Here’s you need to know about blister packs and what sets this technology apart. What Is Blister Packaging? Blister packaging, or blister packs, are a type of plastic packaging molded to the shape of a specific product and sealed to a backing or lidding structure. The backing is traditionally made from paper, foil, or plastic. Blister packaging was originally named for the appearance of the individual plastic bubbles that capsules were contained in. Since then, their usefulness and industrial application have expanded. Other than pharmaceuticals, blister packaging can be a practical option for food, hardware, electronics, and writing tools to name a few. Why Is Blister Packaging Used? Blister packaging is extremely versatile and has usefulness in a wide range of industries. Food benefits from reduced air exposure, helping to maintain freshness. Delicate objects such as electronics benefit from the sturdiness and tight fit of the packaging. Cosmetics, sports equipment, toys, and tools are less likely to be lost or stolen because of the unusual shapes of objects packaged in this manner. Compared to boxed products, transparent blister packaging can showcases a product visually and increases shelf appeal. Blister packaging allows either the manufacturer or retailer to include promotional materials or advertisements to help build a brand awareness. Blister packaging helps shoppers see product, further aiding in their purchase decision while keeping the product protected and the packaging free of damage.

  • Recycled plastic is not just a low-end replacement for virgin plastic
    Recycled plastic is not just a low-end replacement for virgin plastic
    April 09, 2026
    Guangzhou Rosin Packaging Co., Ltd. has developed an injection grade low precipitation, low-temperature resistant recycled PP material using food grade recycled polypropylene as raw material, through three-stage heat treatment and low-temperature blending modification technology. This material has passed FDA, ROHS, REACH contact safety testing and has an impact strength of over 3 kJ/m ² at -15 ℃, far exceeding that of homopolymer PP-H raw materials. It completely solves the problem of unstable adhesion during secondary processing and provides a high-performance solution for the low-carbon transformation of the daily chemical packaging industry. Industry pain points: Dual constraints of low-temperature brittleness and precipitation issues In the field of plastic packaging and products, homopolymer polypropylene occupies an important position due to its excellent hardness and transparency, and is widely used in packaging scenarios such as food, daily chemical, pharmaceutical, etc. However, its low-temperature brittleness issues constrain its application boundaries. When the ambient temperature drops from 23 ℃ to 0 ℃, the notch impact strength of PP-H cantilever beam sharply decreases from about 3 kJ/m ² to 1.5 kJ/m ², and further drops to 0.7 kJ/m ² at -15 ℃. This performance cliff makes PP-H products prone to cracking in winter, which not only affects the user experience but also increases the external packaging and after-sales costs of the enterprise. Polypropylene materials also commonly face the problem of precipitation. Residual small molecule substances such as ethylene monomers, lubricants, and release agents in raw materials will migrate to the surface of the product over time, seriously affecting the adhesion of secondary processing such as spraying, electroplating, printing, and hot stamping. Many companies have encountered the embarrassing situation of good adhesion during the initial spraying stage, but failure in the hundred grid test after one month of storage. What is even more troubling is that the differences in precipitation tables between different petrochemical grades or even different batches of the same grade seriously interfere with production stability and quality control consistency.
