Thermoforming Films in Food Packaging

As we know, packaging plays a vital role in today’s fast-paced food industry. Packaging is more than just wrapping a product – it protects, preserves, presents, and even acts as a branding tool. One of the best and unknown heroes behind this packaging is thermoforming films in food packaging.

These films are the reliable choice for manufacturers or distributors in creating vacuum packs, trays, and sealed containers that store and showcase food safely and attractively.

But have you ever thought what exactly thermoforming films are? Why do food manufacturers and distributors rely on them? And how can you choose the right thermoforming films for the food packaging of your products?

Let’s break it all down!

What Are Thermoforming Films?

Thermoforming films are thin plastic or polymer sheets that become moldable when heated. Once these films are heated, they form a specific shape using vacuum or pressure. Typically, it is used for wrapping perishable food items such as chicken pieces, cheese, sausages, & more. These films can be rigid, semi-rigid, or flexible. 

Here, Bagla Group also offers types of thermoforming films for packaging meat, seafood, dairy, ready-to-eat meals, and many other perishable food products.

Why Do Thermoforming Films Matter in Food Packaging?

When a food manufacturer, distributor, or packer uses thermoforming films in food packaging then they find various functional, economic, and aesthetic benefits. These films are crucial in food packaging because of the transparency matter in food packaging, and other factors are as follows:

  • Extend the shelf life of the product by using the vacuum and MAP (modified atmosphere packaging) technology.
  • Protect products against contamination, puncture, and spoilage.
  • Visual appealing with clear, glossy, or printable finishes.
  • For better product fit and branding offers custom shapes and sizes.
  • Hygiene & Compliance with global food safety standards

Thermoforming films are flexible and a safe food brands need for packaging premium seafood or frozen ready meals.

How Does Thermoforming Film in Food Packaging Work? (Step-by-Step)

Here you will get a simplified breakdown of the thermoforming films in the food packaging process:

  1. Heating – A plastic film is fed into a thermoforming machine and heated until it becomes pliable.
  2. Forming – This heat film is shaped into the particular product using vacuum or pressure forming.
  3. Cutting & Output – The final packs are trimmed and discharged for storage, shipping, or retail display.

Materials Used in Thermoforming Films

All the thermoforming films are not created equal. As per the packaging needs, the thermoforming films are made from various types of packaging film materials depending on the packaging needs. Here are the most common:

  • PET (Polyethylene Terephthalate)
  • PP (Polypropylene)
  • PE (Polyethylene)
  • PA (Polyamide / Nylon)
  • EVOH (Ethylene Vinyl Alcohol)
  • PVC (Polyvinyl Chloride) – Less Common Today

Types of Thermoforming Films

There are multiple types of thermoforming films. These films are categorized by barrier properties and structure:

  • High-Barrier Thermoforming FilmsThese barrier films are designed for products requiring long shelf life. Crystalform HB can simply block the oxygen, moisture, and UV. Films are used in vacuum packs and MAP packaging for meat and seafood.
  • Medium-Barrier Thermoforming FilmsThese films are the reliable option for the short-to-mid shelf life items like dairy, fresh pasta, or daily items. A cost-effective solution without sacrificing much protection.
