Blister packing is quintessential in functioning as the primary package for many over the counter medicines and is increasingly gaining traction as a process that adds value to the end product in the food and electronics industry. Thanks to the protection from pre-emptive tampering and the ease of seeing the product offered, the blister offers superb image for product packaging, making it ubiquitous. Along with the popularity, the use of blister packaging comes a complex challenge of meeting customer requirements and regulatory standards for quality which is resolved by blister packaging manufacturers who design, engineer and produce packing at a scale suitable for retail.
What Is Blister Packaging?
Blister packing is a class of preformed plastic packaging that is used for small consumables ranging from food items, pharmaceuticals and even medicine. It includes a dome or pocket that securely and protectively contains the product ranging from ranged goods to smaller devices. It usually consists of a cavity or pocket made from thermoformed plastic, usually sealed to a backing of paperboard, aluminum foil or plastic, making it easy to store or sell in retail.
Blister packs are widely used in pharmaceutical packaging to protect and control dosage for unit-dose packaging of tablets, pills, and lozenges. Additionally, in retail packaging, blister packs serve to showcase and contain items such as batteries, toys, tools, and electronics.
Blister Packaging Types
Blister packaging includes various designs tailored to specific requirements of an industry or product:
1. Face Seal Blister: A card that covers the face of the product has a clear plastic blister sealed to it.
2. Full Face Seal Blister: For more security and visual appeal, the blister covers the entire face of the card.
3. Trapped Blister: Improves tamper evidence and environmental appeal, the blister is sandwiched between two cards.
4. Slide Blister: The card does not seal to the blister and can slide in and out, this is helpful for reusable packaging.
5. Clamshell Blister: Foldable hinged blisters commonly found in tools and electronics packaging.
6. Pharmaceutical Blister Pack: Backed with aluminum foil, it has many cavities for tablets or capsules.
