How to Choose the Right Film for Jelly Pouch Packaging

The choice of the right film for jelly pouch packaging is crucial to ensure the quality and preservation of your product. With a wide range of options available, selecting the most suitable film for your specific needs can be challenging. To guide you in making an informed decision, this article provides a comprehensive overview of the key factors to consider when choosing a film for jelly pouch packaging.

Film Type and Properties

The type of film you choose depends on the characteristics and requirements of your product. Common types of films used for jelly pouch packaging include:

– Polyester (PET): PET is a versatile film with excellent clarity and mechanical strength. It is heat-sealable and provides good barrier properties against moisture and oxygen.

– Polyethylene (PE): PE is a flexible and lightweight film. It offers high puncture resistance and is suitable for packaging irregular-shaped products.

– Polyethylene Terephthalate Glycol (PETG): PETG combines the properties of PET and PE. It has good clarity, is heat-sealable, and provides enhanced flexibility.

Barrier Properties

The barrier properties of the film are essential in protecting the jelly from external influences and maintaining its shelf life. Consider the following factors when evaluating barrier properties:

– Oxygen Transmission Rate (OTR): This measures the amount of oxygen that passes through the film over time. A lower OTR indicates better barrier properties against oxygen.

– Moisture Vapor Transmission Rate (MVTR): This measures the amount of moisture that passes through the film over time. A lower MVTR indicates better barrier properties against moisture.

Mechanical Properties

The mechanical properties of the film determine its durability and resistance to damage during packaging and handling. These properties include:

– Tensile Strength: This measures the force required to break the film. A higher tensile strength indicates greater resistance to tearing and stretching.

– Puncture Resistance: This measures the force required to puncture the film. A higher puncture resistance ensures protection from sharp objects.

– Impact Strength: This measures the film’s ability to withstand sudden impacts. A higher impact strength prevents the film from cracking or tearing during transportation.

Sealability and Adhesion

The sealability of the film is crucial for ensuring the integrity of the package. Consider the following factors:

– Heat-Sealability: The film should seal effectively when exposed to heat. Look for films with a low sealing temperature to prevent damage to the product.

– Adhesion: The film should adhere well to itself and to other materials used in the packaging process. Good adhesion ensures a strong and durable seal.

Other Considerations

In addition to the key factors discussed above, consider the following:

– Cost: The cost of the film is an important consideration. Choose a film that meets your performance requirements without exceeding your budget.

– Environmental Impact: Opt for films that are recyclable or biodegradable to reduce waste and promote sustainability.

– Printing Quality: If you plan to print on the film, ensure it has good printability to achieve clear and vibrant designs.
