Materials for Blow Molding

When it comes to blow molding, different plastics can be used. Choosing the correct resin for the process can be challenging, and so our team can help you design custom carrying cases that are made through injection molding. Choosing a plastic resin will drastically alter cost, flexibility, strength, and density. Below, we will give a general outline of the most common type of plastics used during the blow molding process.

High-Density Polyethylene is the most popular plastic for the blow molding process. The plastic is easily moldable, and it can also be easily colored with vibrant colors. The plastic is also chemically inert (rated by FDA).

Low-Density Polyethylene comes in varying types. All are relatively soft but require incredibly high levels of stress to crack or flex.

Polypropylene is the 2nd most commonly used plastic for molding. It is a stiffer plastic than HDPE. It also has a low-density rating.

Above is a small list of plastics that can be used for blow molding and injection molding. To find out more information about our full line of materials, please give us a call. We can help you create custom carrying cases for any devices or products you need to carry. Call us today.
