1. What is the difference between blister packaging and clamshell packaging?

Blister packaging is regularly used in the medical and pharmaceutical industries and many more. This packaging is excellent at sealing and keeping sterile pills and other pharmaceutical safe. On the other hand, clamshell packaging has hinges that enable them to open like a clamshell. A clamshell package usually includes a hanger tab so it can be displayed on a store shelf.

At PT Print Co, we solely produce and supply blister card packaging.

2. What is a blister package?

Blister packaging is commonly used in the medical and pharmaceutical industries and many others. This type of packaging is excellent at sealing and keeping sterile pills and other pharmaceutical safe.
Blister packaging is also commonly used in retail packaging but usually small consumer goods, food, and electronics, etc… The main difference between a blister and a clamshell is that a blister doesn’t have a hinge. Blisters are usually attached to a paperboard card (header card) where the “blister” holds the product in place. Blisters are also great for showcasing products because their clarity leads to great visibility for the product.

3. What is thermoforming?

Blister packaging and clamshell packaging are made from a process called thermoforming. Thermoforming is the process of heating rigid plastic into a softened state, then cooling it back into a rigid state, around a mold, with the use of vacuum. This allows blister or clamshell packaging to be formed into virtually any shape.

4. Why should a manufacturer consider using a blister package or a clamshell package?

A blister or clamshell should be considered whenever there is a need to protect, contain, transport or merchandise an item.

5. What is the best use of a blister package?

A blister is a single, vacuum-formed shell that can contain and merchandise a consumer product, after it’s sealed to a header card. Blisters are commonly used on consumer product packages that have a relatively low value. A tape measure is frequently packaged in a blister package while an expensive automotive part may be packaged in a clamshell package.

6. Are there any size limitations to clamshell or blister packaging?

Clamshell or blister packaging can have little restrictions on size. Limitation on size will be determined by machinery and tooling. Most consumer and industrial products can be accommodated, particularly, if they are of the size and weight that can be hung from a display peg.

7. What is your blister card packaging made out of?

Our blister card packaging is made special from PET (Polyethylene terephthalate) and PVC plastic thermoforming with respective coating.

Blister packs eliminate the need for additional cartons, thereby reducing the cost of packaging. For more information about the material, you may reach out to us via email.

Blister packs are used to package products such as toys, hardware, medication, pharmaceuticals products.

9. Do you offer samples?

Yes, we do. We can send generic samples to you upon request. Samples are made by using digital print.

10. What is the minimum order?

In general our minimum order quantity is between 5 thousand to 10 thousand units. Because we are a custom manufacturer we can quote any size order. However, lesser are generally hand-made which means higher labor costs. As with all manufacturing higher quantities = lower unit costs. Most box constructions require a certain amount of order quantity to be machine run due to set-up required.
