Understanding Thermoforming, Vacuum, and Blister Packaging Knives

Wondering how you can get the best machine knives for thermoformed packaging, vacuum packaging, and blister packaging? In this blog, we’ll help you learn more about the unique challenges posed by these packaging materials, and how we can help you get the high-quality knives you need for consistent product quality. Let’s get started.

The Unique Challenges Of Vacuum Packaging Knives

First, let’s start with vacuum packaging. Vacuum packaging has a number of benefits – it helps save space, and it also is ideal for preserving food products, and providing them with an extended shelf life.

But if you plan on creating vacuum packaged products, you need to make sure you have the right machine knives. Typically, the plastic film used to create vacuum packaging materials is 3 to 4x thicker compared to traditional shrink-wrap and other commonly-used wrapping materials.

This can make the film more difficult to cut – and if you don’t have sharp, long-lasting machine knives for your vacuum packaging units, you may encounter QA difficulties after long production runs.

The Importance Of High-Quality Thermoformed & Blister Packaging Knives

Vacuum packaging isn’t the only challenging packaging material – thermoformed materials and blister packaging can also be very difficult to cut properly, due to the more brittle and tough nature of the plastic film and sheeting used for this type of packaging.

It’s important to be able to cut cleanly through thermoformed and blister packaging without damaging the product itself – and that means you need to optimize the tooth profile of your blades, choose the right material for your machine knives, and work with a high-quality supplier like TGW International for consistent, reliable results.
