Polyvinylidene chloride (PVDC) printing film is well – known for its excellent barrier properties against oxygen, moisture, odors, and flavors. This makes it a popular choice in various packaging applications, such as food, pharmaceutical, and consumer goods packaging. As a supplier of PVDC printing film, I understand the importance of choosing the right lamination materials to enhance the film’s performance and meet the diverse needs of our customers. In this blog, I will discuss some of the lamination materials that are suitable for PVDC printing film. Polyvinylidene Chloride Printing Film
1. Polyethylene (PE)
PE is one of the most commonly used lamination materials for PVDC printing film. It comes in different densities, including low – density polyethylene (LDPE), linear low – density polyethylene (LLDPE), and high – density polyethylene (HDPE).
- LDPE: LDPE has good flexibility, transparency, and sealing properties. When laminated with PVDC printing film, it can provide a soft and conformable packaging solution. It is often used in applications where flexibility is crucial, such as for packaging of fresh produce, snacks, and some soft – packed foods. The low melting point of LDPE allows for easy heat – sealing, which is an important characteristic in packaging operations.
- LLDPE: LLDPE combines the advantages of both LDPE and HDPE. It has excellent tensile strength, puncture resistance, and tear resistance compared to LDPE. When used as a lamination material for PVDC printing film, it can improve the overall durability of the packaging. This is particularly useful for products that may be subjected to rough handling during transportation and storage. For example, in the packaging of frozen foods, the LLDPE – laminated PVDC film can better withstand the stresses associated with freezing and thawing cycles.
- HDPE: HDPE offers high stiffness, excellent chemical resistance, and good moisture barrier properties. Laminating PVDC printing film with HDPE can result in a rigid packaging structure, which is suitable for products that require a more robust container. For instance, in the packaging of some pharmaceutical products or household chemicals, the HDPE – laminated PVDC film can provide a reliable and protective packaging solution.
2. Polypropylene (PP)
PP is another popular lamination material for PVDC printing film. It has several advantages, including high clarity, good heat resistance, and excellent mechanical properties.
- Biaxially Oriented Polypropylene (BOPP): BOPP is widely used in packaging due to its high transparency, gloss, and stiffness. When laminated with PVDC printing film, it can enhance the visual appeal of the packaging. The high – quality printability of BOPP also allows for vivid and sharp graphics, which is important for product branding and marketing. BOPP – laminated PVDC film is commonly used in the packaging of confectionery, tobacco, and some high – end consumer goods.
- Cast Polypropylene (CPP): CPP is known for its good heat – sealing properties and flexibility. It can be used as a heat – sealing layer when laminated with PVDC printing film. The combination of PVDC and CPP can provide a packaging solution with both excellent barrier properties and easy – to – seal characteristics. This is suitable for applications where a reliable seal is required, such as in the packaging of liquid – containing products or granular materials.
3. Polyester (PET)
PET is a strong and dimensionally stable material with good temperature resistance and excellent clarity. As a lamination material for PVDC printing film, it can add strength and durability to the packaging.
- Biaxially Oriented Polyester (BOPET): BOPET has high tensile strength, good barrier properties against oxygen and moisture, and excellent resistance to chemicals and solvents. When laminated with PVDC printing film, it can provide a high – performance packaging solution for products that require long – term protection. For example, in the packaging of coffee, tea, and some high – value food products, the BOPET – laminated PVDC film can effectively preserve the flavor and quality of the contents by preventing the ingress of oxygen and moisture.
- Amorphous Polyester (APET): APET is a clear and flexible material with good formability. It can be used in applications where a combination of transparency and flexibility is needed. Laminating PVDC printing film with APET can result in a packaging structure that is suitable for products like cosmetic samples or small – sized consumer goods, providing both protection and visibility.
4. Aluminum Foil
Aluminum foil is an outstanding barrier material against oxygen, moisture, light, and odors. When laminated with PVDC printing film, it can significantly enhance the film’s barrier properties, making it suitable for applications that require high – level protection.
- Thin Aluminum Foil: Thin aluminum foil (usually with a thickness of around 6 – 9 microns) can be laminated with PVDC printing film to form a high – performance packaging barrier. This type of laminate is commonly used in the packaging of sensitive products such as pharmaceuticals, military rations, and some high – end food items. The aluminum foil layer blocks out light, which can prevent the degradation of light – sensitive substances, and also provides an almost complete barrier against oxygen and moisture.
- Aluminum Foil Laminates with Other Layers: In some cases, aluminum foil can be part of a multi – layer laminate that also includes other materials like PE or PET in addition to PVDC printing film. This multi – layer structure can combine the advantages of different materials, providing a comprehensive packaging solution with excellent barrier, mechanical, and sealing properties.
5. Paper
Paper is a sustainable and widely used packaging material. When laminated with PVDC printing film, it can combine the natural look and feel of paper with the excellent barrier properties of PVDC.
- Kraft Paper: Kraft paper is strong and durable. Laminating PVDC printing film with kraft paper can result in a packaging material that is suitable for products like pet food, dry goods, and some industrial products. The PVDC layer provides the necessary barrier against moisture and oxygen, while the kraft paper gives the packaging a sturdy and eco – friendly appearance.
- Coated Paper: Coated paper has a smooth surface, which is suitable for high – quality printing. When laminated with PVDC printing film, it can create an attractive and functional packaging solution for products such as luxury food, cosmetics, and stationery. The PVDC layer enhances the barrier properties, and the coated paper allows for vivid and detailed printing of product information and branding.
6. Considerations for Choosing Lamination Materials
When choosing lamination materials for PVDC printing film, several factors need to be considered:
- Product Requirements: The nature of the product being packaged is the most important factor. For example, food products may require materials that are food – safe and have excellent barrier properties to maintain freshness. Pharmaceutical products need materials that can protect against moisture, oxygen, and light to ensure the stability of the drugs.
- Processing Compatibility: The lamination process should be compatible with both the PVDC printing film and the lamination material. This includes factors such as temperature, pressure, and adhesive compatibility. For example, some materials may require specific adhesives or lamination techniques to ensure a strong and durable bond.
- Cost – effectiveness: Balancing the cost of the lamination material with the performance requirements is crucial. In some cases, a lower – cost material may be sufficient to meet the product’s needs, while in other cases, a higher – end material may be necessary for long – term product protection.
- Environmental Impact: With the increasing focus on sustainability, the environmental impact of the lamination materials should also be considered. Materials that are recyclable, biodegradable, or made from renewable resources are becoming more popular in the packaging industry.
