Custom Thermoforming Materials

Custom thermoforming serves a variety of industries. Its versatility is due to the process, which can work with a variety of plastics. Focusing on molding heated plastic, thermoforming is a growing industry serving many other industries, from healthcare to technology. Packaging systems can communicate value to customers. Custom thermoforming is an ideal solution that protects and organizes materials, creating a great experience for users. The aeasthetics don’t stop there, with a variety of plastics used for thermoforming.

These plastic thermoforming materials each have their own qualities and benefits.  Here’s a rundown of some of the materials with which we work at Sunrise Packaging (Blaine, Minnesota). 

Custom Thermoforming Materials & Properties

PET (Polyethylene Terephthalate)Thermoformend trays for the health and beauty products.

PET is a super-clear material, affording customers a great view of a product (we love it for custom vacuum-forming in retail packaging). Another reason why it’s popular? It’s easily recyclable. 

PVC (Polyvinyl Chloride)

PVC is one of the strongest custom thermoforming materials, but just as malleable as any other. PVC is versatile in other ways as well. It can be translucent or colored, opaque or clear. It’s also recyclable, of course. 

 PETG (modified Polythylene Terephthalate)

PETG is a modified version of PET that turns it it into a cross between PET and PVC.  It has a lower melting point than PET, and retains the strength and versatility of PVC. 

RPET (Recycled Polyethylene Terephthalate)

Noticing a trend? PET is a popular base for custom thermoforming. This version–RPET–is made from recycled PET. It’s slightly weaker than standard PET, though. 

PS (Polystyrene)

Polystyrene is among the hardest and stiffest custom thermoforming materials. It’s a popular option for anything that needs to be punched or cut (think CD cases, smoke detectors, etc). 

Custom Thermoforming Applications

These different materials each have slightly different benefits and uses. Depending on what you need from your packaging, Sunrise can recommend the perfect solution.  Contact us today to learn more!

Putting Poly into Packaging

Packaging can take many forms and can be made out of many different materials. One popular choice is the use of poly. Poly is a flexible material, making it durable against everyday use. Poly packaging is very versatile. Its light weight allows for easy shipping and its many options for design makes poly packaging a must for promotional endeavors. Poly enables packaging to have a crisp and clean look, giving it an excellent presentation factor.

There are two types of poly packaging: polyethylene and polypropylene. Polyethylene is the most popular plastic in the world. It is classified as a thermoplastic, which means it can be melted to a liquid and remolded when it turns solid. Polyethylene is interesting in that it was accidentally discovered. A German chemist in 1898 was applying heat to another compound, when he realized the extreme heat and pressure produced polyethylene. Polypropylene has a little different structure in that it serves as both a plastic and a fiber. It has a higher melting point than many other plastics, making it a common material in dishwasher safe food containers.

Poly packaging is an outstanding choice for customization. Offset and screen printing are popular options for poly projects. Specialty printing like foil stamping, embossing, and debossing are other options to add creativity, uniqueness, and character to any packaging project. Poly packaging can take many forms including boxes, binders, totes, envelopes, and folders. The versatility and durability that poly packaging offers gives companies that ability to stand out from the competition.
