Carded packaging is a type of packaging which includes three subcategories. Skin, blister, and clamshell packaging supplies are widely used across the world, but what are differences between these three items?
From fishing supplies to hardware, from pharmaceuticals to arts and crafts, the applications for these packaging types are virtually endless, but each of them has their own subtle differences and uses.
While all in the same class of packaging supplies, clamshell, skin, and blister packaging are each a unique product in and of themselves. Below we will dive into a broad description of each type of carded packaging, discuss their uses and benefits as well as potential downfalls and environmental impacts.
Skin packaging (also known as skin packs), is a carded packaging supply that places the product contained within on a piece of paperboard. A slim sheet of see-through plastic which covers the product and paperboard backer is then applied.
The paperboard may or may not also have a heat-seal coating. The plastic substrate (LDPE, PVC, ionomer, etc.) is made soft via the use of heat and is then placed over the product on the paperboard backer. Vacuum sealing is occasionally implemented to ensure a tight fit. The substrate then bonds to the heat-seal coating on the paperboard.
Skin packaging looks and feels similar to a blister pack, the notable difference being that the plastic covering the product takes the shape of the product, rather than being pre-formed prior to application.
Plastic film used in skin packaging includes:
Products commonly sold in skin packaging include fish, pork, chicken, beef, tools, hardware and etc. Virtually any object considered a small consumer product can be packaged in these dynamic packaging supplies.
One of the major drawbacks to skin packaging is an experience known as "wrap rage" which is a feeling of extreme annoyance and/or stress from not being able to easily open a product’s packaging and having to utilize scissors or another tool just to remove the packaging from the product.
Of the three carded packaging types we are discussing today, skin packs are perhaps the most troublesome products in this respect. On the other hand, clamshells are probably the easiest type of packaging to open. Clamshells often feature the ability to be easily pulled apart without the need for the intervention of scissors or cutting tools.
The reason skin packaging is often chosen in light of the potential frustrations is that they offer a more secure and tight packaging than both blister or clamshells. When being used for food applications such as the packaging of fish, beef, pork or chicken, they are superior in the protection of the product and the prevention of contamination as they are vacuum sealed and the product contained within is devoid of oxygen.
