1. What are the main packaging types?

Blister packs, clamshell packaging (2-piece clamshells, fold-over &  tri-fold clamshells), thermoformed trays / plastic insert trays;

hinged containers, clear folding cartons, retail POP displays, protective packaging, and more.

For example:

Tri-fold clamshell packaging is designed to fold the clam shell into three sides (front, bottom, back) so that your product can either stand or hang on the display shelf.

  • Pros: There is no need for an additional sealing process, but to make built-in button tabs for easy closing and opening. 
  • Cons: If the product is overweight or the button tabs are not strong, it is easy to bounce off.
  • Solutions: Use a staple when necessary or make more button tabs.

2. What are commonly used materials for thermoforming?

The commonly used materials are PVC ( the density is 1.36 g/cm3), PS ( the density is 1.06 g/ cm3), PET (the density is 1.39 g/ cm3), PP ( the density is 0.92 g/ cm3)

  • Polyvinyl chloride (PVC)
  • Polystyrene (PS)
  • Polyethylene terephthalate (PET)
  • Polypropylene (PP)
  • Polyethylene (PE)

The thickness of thin-gauge thermoformed packaging is generally between 1 – 2 mm or thinner. Among them, the maximum thickness of PVC is generally 0.8 mm, and Polystyrene is generally up to 2.2 mm. If the maximum thickness is exceeded, the plastic sheet is difficult to pull and the equipment will also be damaged.

The color of the material is usually transparent or natural. Customized color is available according to your requirements.

3. What are the advantages of thermoforming packaging?

In terms of thermoforming production, the tooling cost is lower than other production techniques such as injection molding. And the lead time is shorter. What’s more, it can deliver custom prototyping in a quick and inexpensive way.

In terms of packaging, it can display your product clearly with great visibility. At the same time, these clamshells and boxes play a good role in merchandising with a hanging or standing design.
