Introduction
A type or kind of plastic packaging that is used for small consumer goods and also for pharmaceutical goods is known as blister packaging. Most of the time, blister packaging is made from thermoformed plastics. Also, you should know that blister packs are supported by aluminium foil, paperboard, and other kinds of plastic sheets. One of the most common queries that arises is: where is blister packaging, also known as Plastic Blister Packaging, used? Unit dose packaging is also known as blister packaging and is mostly used in the pharmaceutical industry for packing medicine. In this method of packaging, a plastic sheet is used as a thermoform to create several cups or blisters that can hold the product.
Theft Safety Blister Packaging
In several areas, blister packaging is used, not just in pharma. One of the amazing things that you will know about blister packaging is that it is low-cost, cannot be tampered with, is theft-preventive, and gives good protection. Let’s look at the physical properties of blister packaging. It is made from several kinds of polymers, like COP, PVC, PCTFE, PVDC, and some others. The most common kind of blister packaging material is PVC, also known as polyvinyl chloride. Plus, the manufacturers of blister packaging use a kind of cold-form packaging that is made from polyamide, aluminium, and PVC.
Blister Packaging Is Water Resistant.
What protects the blister packaging is the thermoformed polymer, which keeps the inner contents safe from water, water vapour, or any other kinds of liquids. But the rear cover is also pivotal, on which the degree of resistance of water or any other liquid is highly dependent. If, in blister packaging, you are using a paper-based sheet for the lid at the rear, then the water resistance is tainted. Another important thing that you will note about the blister packaging is that it offers an excellent barrier against moisture and oxygen. The barrier properties of the blister packaging enhance as the process of manufacturing puts in more layers of polymers for the blister packaging. The next feature is UV protection. You can control the transparency of the blister packaging, and therefore, how much UV radiation or rays get into the packaging. It has metalized PVC, which will fully block the UV rays and enhance the shelf life of products or goods that are perishable.
Blister Packaging Protects Your Goods
One of the best things that you will know about blister packaging is that it can hold things, items, products, or delicate in place and protect them from drops, bumps, and scratches. The hard layer of outer polymer protects the product from any kind of damage. Next, the blister packaging is tamper-evident. Also, the packaging cannot be reused. Once the blister packaging is opened or uncovered, you cannot close it easily. Blister packaging is one such example that requires tools to open. Plus, it also consists of the visibility of the products that are packed. So, the consumer can now make choices that are well-informed before buying the products. So, when you are buying medicines, blister packaging helps you look at and identify the medicines.
Merits And Demerits of Blister Packaging
Blister packaging is mainly used in several industries, including pharma and food. But it is also used for the packaging of stationery, home improvement tools, electronics, and much more. Even after being the most low-cost packaging, the poor implementation of blister packaging has most of the time caused issues in wrapping. It requires a good sealing tool. Metallized plastic sheets that are used for some of the types of packing are not recyclable. Plus, to make sure that your blister packaging is effective, use a good backing.
