PET heat sealable film

Introduction

 

Heat sealable PET films are made from polyethylene terephthalate (PET), a thermoplastic polymer known for its excellent mechanical properties, chemical resistance, and transparency. These films are specifically designed to be heat-sealable, so they can be easily sealed using heat and pressure. This property makes them ideal for a variety of packaging applications where a tight seal is required to protect the contents from moisture, oxygen, and other contaminants.

 

Properties of Heat Sealable PET Film

 

High Transparency
Heat sealable PET film have a high degree of transparency, allowing consumers to see the contents of the package clearly. This is particularly important for products where appearance is a key selling point, such as food, cosmetics, and pharmaceuticals. The transparency of PET films also makes it easy to inspect the contents for quality control purposes.

Excellent Barrier Properties
These films offer excellent barrier properties against moisture, oxygen, and odors. This helps to extend the shelf life of packaged products by preventing spoilage and degradation. For example, in food packaging, heat sealable PET films can keep food fresh for longer periods by preventing the ingress of moisture and oxygen, which can cause mold growth and oxidation.

Heat Sealability
As mentioned earlier, heat sealable PET films are easily heat-sealable. This property allows for efficient packaging processes, as the films can be sealed quickly and securely using heat and pressure. The heat sealability also ensures a tight seal, which helps to prevent leakage and contamination of the packaged product.

Chemical Resistance
Heat sealable PET films are highly resistant to chemicals, making them suitable for packaging a wide range of products. They can withstand exposure to acids, bases, and solvents without deteriorating or losing their barrier properties. This makes them ideal for packaging chemicals, pharmaceuticals, and other products that may come into contact with harsh substances.

Mechanical Strength
Heat sealable PET films have good mechanical strength, which means they can withstand handling and transportation without tearing or breaking. They are also resistant to puncturing and abrasion, providing additional protection to the packaged product.BOPET Film

 

Types of Heat sealable PET film

 

Heat sealable PET film
This is the most common type of PET heat seal film. It is used for a wide range of packaging applications, including food, pharmaceuticals, cosmetics, and electronics. heat sealable PET films are available in different thicknesses and widths to meet the specific needs of different applications.

PET Sealing Film
PET sealing film is similar to Heat sealable PET film, but it is designed for applications where a stronger seal is required. It is often used for packaging heavy-duty products or products that need to be protected from extreme conditions.

PET Anti-Fog Film
This type of PET heat seal film is coated with an anti-fog agent, which prevents condensation from forming on the inside of the package. This is particularly useful for packaging products that are sensitive to moisture, such as fresh produce, meat, and dairy products.

PET Easy Peel Film
PET easy peel film is designed to be easily peeled open by consumers. It is often used for packaging products that need to be opened frequently, such as snacks, coffee, and tea. The easy peel feature makes it convenient for consumers to access the product without having to struggle with difficult-to-open packaging.

Food Packaging
Heat sealable PET films are widely used in the food industry for packaging a variety of products, including snacks, baked goods, fresh produce, and frozen foods. The high transparency of these films allows consumers to see the food inside, while the excellent barrier properties help to keep the food fresh and safe. In addition, Heat sealable PET films can be printed with attractive designs and labels, enhancing the product’s visual appeal and marketing potential.

 

For example, heat sealable PET films are commonly used for packaging potato chips. The films provide a tight seal that prevents the chips from becoming stale or absorbing moisture. They also protect the chips from physical damage during transportation and storage. Similarly,heat sealable PET filmsare used for packaging fresh fruits and vegetables. The films help to maintain the freshness and quality of the produce by preventing the loss of moisture and the ingress of oxygen.PET heat seal film

 

Pharmaceutical Packaging
In the pharmaceutical industry, heat sealable PET films are used for packaging tablets, capsules, and other medications. The excellent barrier properties of these films help to protect the drugs from moisture, oxygen, and light, ensuring their stability and efficacy. Heat sealable PET films can also be sterilized using various methods, making them suitable for packaging sterile products.

 

For instance, heat sealable PET films are used for blister packaging of tablets. The films form a tight seal around the tablets, protecting them from moisture and oxygen. The blister packs can be easily opened by consumers, while still providing a high level of protection to the medication.

Cosmetic Packaging
Heat sealable PET films are popular in the cosmetic industry for packaging products such as creams, lotions, and perfumes. The high transparency of these films allows consumers to see the product inside, while the excellent barrier properties help to preserve the quality and freshness of the cosmetics. PET heat seal films can also be printed with attractive designs and labels, enhancing the product’s visual appeal and marketing potential.

 

For example, heat sealable PET films are used for packaging facial creams. The films provide a tight seal that prevents the cream from drying out or being contaminated. They also protect the cream from exposure to light and air, which can cause degradation of the active ingredients.

 

Electronics Packaging
Heat sealable PET films are used in the electronics industry for packaging sensitive electronic components such as integrated circuits, capacitors, and resistors. The excellent barrier properties of these films help to protect the components from moisture, dust, and static electricity. Heat sealable PET films can also be printed with identification marks and barcodes, making it easy to track and manage the components during production and distribution.

 

For instance, heat sealable PET films are used for packaging microchips. The films provide a tight seal that protects the chips from physical damage and contamination. They also help to prevent static electricity buildup, which can damage the sensitive electronic components.PET lidding film

 

Benefits of PET Heat Seal Films

 

Enhanced Product Protection
