Blister packs have a variety of uses and are primarily used to protect sensitive products for an extended time. Many people recognize these packages as they are often used for pharmaceuticals. However, they can also be used for other consumables such as food, tools, and toys. They also provide cost-effective packaging with good durability. Additionally they can extend the life of, for example, pharmaceutical drugs as they protect against moisture, and tampering.
Blister packs for pharmaceuticals
Blister packs are very popular in the pharmaceutical industry as they have good protection against moisture and mold. They also give the products a noticeably longer shelf life. The packages are shaped according to the medicine it is to contain. They are then laminated with a thin layer of aluminum.
Other types of blister packs
In addition to medication blister packs, these types of packages can be made in other shapes to suit other uses too. The simplest are those that are shaped like a bubble over the product and glued with the backside. However, there are also both folded blisters and eco-blisters. Folded blisters can be opened and closed by folding the front and back. The packaging then closes automatically and makes it quick and easy to package your goods. Eco-blisters are similar to the one with the plastic bubble, except that it is instead folded over a piece of cardboard that closes the package.
The advantage of blister packs is that they can be adapted with the desired resistance to avoid the packs being tampered with. When packing products that are at risk of theft and/or damage, the packaging can be produced with a tougher resistance to make it more difficult to open by hand.
Recycling and sorting
Today, it is important to recycle plastic packages that are no longer used. This is to create a more sustainable environment, where instead of incineration we can reuse old plastic packaging for new ones.
Blister packs are sorted mainly based on the material it is mostly made of, i.e., plastic. Even if blister packs for pharmaceutical drugs have a layer of aluminum, they are still sorted at source as plastic as there is so little aluminum on them. The products that have cardboard (e.g., Eco-blister) should, however, be sorted as both plastic and paper.
