How Thermoforming Films Are Made? Process & Applications

Are you a manufacturer of food items, looking to enhance your packaging to extend product shelf life, hygiene, and shelf appeal? This is where Thermoforming Film steps in as a core packaging solution, which helps brand standout in the modern food industry. 

These Barrier Films combine properties like high barrier protection, durability, and high clarity, making them ideal for preserving the freshness and improving the visual appeal of the product.

In this blog, you will get to know the complete process of how Thermoforming Films are made in the Bagla-Group manufacturing unit.

So, just dive into the reading to understand the features, quality, and scientific facts related to the Thermoforming Films to enhance the food shelf life & freshness.

What Are Thermoforming Films?

Thermoforming Films are thin plastic films used to package food products. These films are highly in demand because they can be heated and molded into specific shapes to form a shape according to the product. 

At Bagla Group, we design and manufacture custom films to meet the customer’s requirements. To meet the various industry demands, Thermoforming Films have various quality as vacuum skin packaging, modified atmosphere packaging (MAP), and deep-draw tray sealing.

How Thermoforming Films Are Made? (Manufacturing Process)

To understand the process of how Thermoforming Films are made, we have divided these stages into 6 key points.

1. Material Selection & Resin Blending

The journey of the manufacturing of Thermoforming Barrier Films begins with the selection of the right polymers. Depending on the end-use, we may use a single material or co-extrude multiple layers. Common resins include:

• Polyethylene (PE): Excellent flexibility and sealability
• Polyamide (PA): High puncture resistance and durability 
• Polypropylene (PP): Great for high-clarity applications
• Ethylene Vinyl Alcohol (EVOH): Provides a superior oxygen barrier

At Bagla Group, we work with high-purity, food-safe resins to ensure compliance with international safety standards.

2. Coextrusion Using Advanced German Technology

Bagla Group produces advanced Thermoforming Films using German coextrusion technology, which allows multiple polymer layers to be combined in a single, continuous process.

• Coextrusion means two or more molten polymers are extruded simultaneously through a specialized die head to form a multilayer structure.
• Each layer serves a unique purpose, such as barrier protection, sealing capability, or mechanical strength.
• This technology ensures excellent layer adhesion, uniform thickness, and customized performance for diverse applications.

3. Water Quenching & Cooling

Immediately after extrusion, the molten film passes through water quenching machines. This rapid cooling process is crucial as it:

• Locks in the film’s clarity and gloss
• Enhances mechanical strength
• Maintains uniform thickness
• Prevents crystallization defects

Water quenching ensures the film achieves high transparency and smooth surface finish, which is essential for attractive product presentation.

5. Surface Treatment

Corona or chemical treatment may be applied to improve printability and lamination performance for branding and labeling applications.

5. Slitting & Rewinding

Once the Thermoforming Films are processed, they are slit into specific widths. Later, they are wound into rolls that fit seamlessly into the automatic thermoforming machines. Bagla Group offers custom roll dimensions and core types to match a wide range of packaging systems used globally.

6. Quality Testing & Packaging

Before dispatch, every batch of Thermoforming Film undergoes rigorous testing:

• Seal strength
• Oxygen & moisture barrier levels
• Clarity and haze
• Tensile and elongation properties

Only when the film meets our stringent standards is it packed and shipped to customers across continents.

List Of Materials Used in Bagla Group Thermoforming Films

For the best output of the Thermoforming Films, Bagla Group customizes materials based on functional, mechanical, and regulatory requirements. We use the products as per the common layers and their purpose. The material is as follows:

We also offer recyclable mono-material solutions for customers aiming for eco-friendly packaging.

As we know, customers are currently aiming for eco-friendly packaging, so keeping this in mind, Bagla Group offers recyclable mono-material solutions.

Which Type Of Thermoforming Films You Can Buy From Bagla Group?

Bagla Group mainly provides three types of Thermoforming Films:

• QuenchTek HB: High Barrier Thermoforming Films are specially designed for meat, seafood, processed food, and vacuum packaging applications that require maximum oxygen and moisture protection.
• QuenchTek MB: Medium Barrier Thermoforming Films are ideal for dairy, bakery, fresh produce, and convenience food packaging where moderate barrier protection and high clarity are required.
• QuenchTek MBPP: PA/PP Medium Barrier Thermoforming Films are specialized Thermoforming Films developed for high-temperature food packaging applications with superior transparency and strong sealing performance.

These Thermoforming Films are manufactured using advanced German water quenching co-extrusion technology for better strength, transparency, and deep-draw performance.
