One way to customize your packaging product is by adding plastic film perforations. TDI creates different types of perforations in all of our custom poly bags, sheeting, and tubing.
Ultimately, ‘the perfect perf’ depends on the gauge, format, and usage of your package. Let’s take a closer look at the varieties and their uses.
What are plastic film perforations?
Perforations are oftentimes called “perfs” in the manufacturing industry. During the process, a die-cut machine punches tiny holes into a sheet of plastic.
These holes are placed next to each other. Their purpose is to make it easy to tear them open.
Types of Perforations
Here are the most common types:
With a straight line of perforations across, either horizontal or vertical, a consumer will have easy access to an item. They can simply rip it open.
Apparently, this type of packaging is designed for single use only since they are not reclosable. Their goal can be for example to safeguard against issues like contamination or fraud.
Easy-Tear versus Hard-Tear:
Easy-tear perforations are openings placed closer together for effortless opening. That is why this type is best for light-weight items, such as feathers.
On the other hand, hard-tear perforations are more spread apart. Since it takes some strength to open them, they are most suitable for heavier materials, like metal screws.
Tear-notch is basically a slit located on one or more sides. It allows the user to simply tear it open. A small slit is all it takes.
How resin material affects the perforation location:
Each type of polyethylene has different characteristics. High-density polyethylene, for example, has more tensile strength. So vertical perforations work best for this type of polymer.
On the other hand, horizontal perforations are most effective in low-density polyethylene.
Plastic Packaging with Perforations
TDI can add perforations to any type of flexible plastic packaging:
- tubing or sleeves
- rolls (bags on rolls)
- individual plastic bags
Usage of Plastic Film Perforations
Perforations are widely used by all kinds of industries. Following are just a few examples:
Medical and Healthcare:
An easy-tear strip will not only make it easier to open up a package, but it will also protect against contamination. During an emergency situation, a staff member will have quick access to a much-needed tool.
Tear notches are widely used to secure safe, single-use food packaging. It guarantees that the content is new, and has not been used yet.
With bags on rolls, a consumer can simply pull off a new bag by tearing along the perforated line. This makes it very convenient to get an individual bag from a roll.
