Push-Through Aluminium Blister Lidding Foil for Capsules and Tablets
(Push-Through Aluminium Blister Lidding Foil) is a high-performance packaging material specifically designed for pharmaceutical products, especially capsules and tablets. The name "Push-Through" refers to the fact that consumers can easily tear open the aluminum film by pressing, allowing them to remove the medication. Typically, this lidding foil is used in conjunction with an aluminum blister base film, providing strong sealing performance to ensure the quality and safety of the medication.
Push-Through aluminum blister lidding foil is suitable for packaging capsules and tablets, designed to allow consumers to easily remove the medication by tearing open the aluminum film. This blister foil has high strength, good airtightness, and high barrier properties, effectively maintaining the freshness of the medication and preventing external contamination.
Push-Through Aluminium Blister Lidding Foil Features
- High Strength: Push-Through aluminum blister lidding foil has very high mechanical strength, able to withstand external pressure and compression, preventing damage or leakage during transportation and storage.
- Good Airtightness and Barrier Properties: This film material has excellent barrier properties against air, moisture, light, and other external contaminants. It effectively extends the shelf life of the medication, maintaining its freshness, preventing moisture, oxidation, or contamination, and ensuring the stability and safety of the medication.
- Easy to Tear Open: The Push-Through film is designed to allow consumers to easily remove the medication through pressing or tearing, simplifying the medication usage process. This design is particularly suitable for packaging capsules and tablets, ensuring that patients can easily and quickly access the medication.
- Excellent Heat Sealing: The aluminum foil can form a reliable seal with the blister base film during the heat sealing process, preventing the medication from coming into contact with the outside world and enhancing the package's airtightness.
- Strong Compatibility: This aluminum foil is suitable for various types of blister packaging equipment, with strong compatibility, meeting the needs of different pharmaceutical manufacturers.
- Convenient Consumer Experience: With the Push-Through aluminum foil, consumers can conveniently and quickly access the medication, especially beneficial for patients who take medication long-term, reducing operational difficulties.
Composition and Structure of Push-Through Aluminium Blister Lidding Foil
- Aluminum Foil Layer: Provides the primary barrier and strength, serving as the core component of the film.
- Polyester or PVC Layer: These layers provide additional mechanical strength and heat sealability, contributing to the stability and sealing of the film.
- Coating Layer: Some Push-Through aluminum films also include specific coatings, such as heat seal coatings or inner coatings, to enhance the sealing effect and protective performance.
Push-through-package Aluminum Foil Type
Push-through packaging is a special type of packaging that allows consumers to easily push out products from the aluminum foil packaging, typically used for tablets, capsules, and certain food items. The aluminum foil used in this type of packaging must be compatible with a variety of materials, including different types of sheet materials such as PVC (Polyvinyl Chloride), CPP (Cast Polypropylene), COC (Cyclic Olefin Copolymer), and A-PET (Amorphous Polyethylene Terephthalate).
| Sheet Type | Key Characteristics | Compatibility with Aluminum Foil |
| PVC | Rigid, transparent, cost-effective, good formability | Excellent adhesion, good moisture protection, suitable for push-through packaging |
| CPP | Flexible, high clarity, moisture and gas barrier | Strong seal, flexible, suitable for push-through packaging |
| COC | High clarity, excellent barrier properties, rigid | Superior barrier, excellent seal integrity, premium performance |
| A-PET | Strong, durable, recyclable, good clarity | Strong seal, moderate barrier, suitable for push-through functionality |
PVC and CPP are widely used for their cost-effectiveness and flexibility, while COC is better suited for high-performance applications where excellent barrier properties are crucial. A-PET is also a good choice for products that require durability and recyclability, although its barrier properties may not be as strong as those of COC. Each material has its advantages, depending on the specific needs of the packaged product.
PVC Sheet (Polyvinyl Chloride)
PVC film is a transparent and rigid material widely used in push-through packaging. It has good formability and strong sealing properties, allowing it to form a firm bond with aluminum foil, providing protection against moisture and gases, making it suitable for pharmaceutical and food packaging. Despite PVC's relatively high rigidity, it still provides sufficient convenience in push-through packaging, making it ideal for products that require easy access. However, PVC contains plasticizers, which may present potential risks in certain applications.
CPP Sheet (Cast Polypropylene)
CPP film is a transparent and flexible plastic material with good transparency and moderate gas barrier properties. When combined with aluminum foil, CPP provides strong sealing and, due to its higher flexibility, is suitable for products that require a softer packaging. Compared to PVC, CPP offers more convenient operation in push-through packaging and effectively protects the product from external environmental factors, making it ideal for products with low to medium moisture and gas barrier requirements.
COC Sheet (Cyclic Olefin Copolymer)
COC film is a highly transparent, high-strength material with excellent gas barrier properties, particularly suitable for products that require long-term protection. It provides superior oxidation resistance and moisture protection compared to PVC and CPP, making it ideal for pharmaceutical and high-end food packaging. Despite its higher rigidity, COC’s formability and sealing properties allow it to form a firm bond with aluminum foil, ensuring easy access to products in push-through packaging while providing excellent appearance and protective performance.
A-PET Sheet (Amorphous Polyethylene Terephthalate)
A-PET film is a highly transparent and mechanically strong plastic material with good thermoformability. It is typically used for packaging that requires clear visibility of contents and offers high durability, suitable for long-term use. When combined with aluminum foil, A-PET provides good sealing and protection against moisture and gases, making it particularly suited for high-quality packaging. Additionally, A-PET is a recyclable and environmentally friendly material, making it commonly used in packaging solutions that meet sustainability requirements.
