As a supplier of blister packaging film, I often encounter inquiries from customers regarding special handling requirements for this product. Blister packaging film is a crucial component in various industries, including pharmaceuticals, food, and consumer goods, due to its excellent barrier properties, transparency, and formability. In this article, I will delve into the special handling requirements for blister packaging film, providing valuable insights for businesses and individuals involved in its use. Blister Packaging Film
Storage Conditions
Proper storage is the first step in ensuring the quality and performance of blister packaging film. The film should be stored in a cool, dry place away from direct sunlight and sources of heat. High temperatures can cause the film to become brittle or lose its flexibility, while excessive humidity can lead to moisture absorption, which may affect the film’s barrier properties and adhesion.
The ideal storage temperature for blister packaging film typically ranges from 18°C to 25°C (64°F to 77°F), with a relative humidity of 40% to 60%. It is also important to store the film in a clean environment to prevent contamination. The film should be kept in its original packaging or a sealed container until it is ready to be used.
In addition, stacking the film rolls properly is essential. Overly tight stacking can cause deformation of the rolls, which may lead to uneven stretching or wrinkling during the forming process. Rolls should be stored horizontally on pallets to prevent damage and ensure easy access.
Handling During Transportation
Transportation is another critical stage in the handling of blister packaging film. During transit, the film is exposed to various environmental factors and mechanical stresses, which can potentially damage the product. To minimize the risk of damage, it is necessary to use appropriate packaging materials and handling equipment.
When shipping blister packaging film, it is recommended to use corrugated cardboard boxes or wooden crates to provide protection against physical impact. The boxes should be labeled clearly with handling instructions, such as "Fragile" or "Keep Dry." Polyethylene bags can be used to wrap the film rolls to prevent moisture ingress and dust contamination.
Vibration and shock during transportation can also cause damage to the film. Therefore, it is advisable to use shock – absorbing materials, such as foam inserts or air pillows, inside the shipping containers. Securing the film rolls properly within the container can also prevent them from shifting and colliding during transit.
Pre – processing Handling
Before using blister packaging film in the production line, several pre – processing handling steps need to be taken. First, the film should be inspected for any visible defects, such as scratches, holes, or uneven thickness. Defective films can lead to production problems, such as poor blister formation or product leakage, and should be removed from the production batch.
It is also important to allow the film to acclimate to the production environment before use. If the film has been stored at a different temperature or humidity level than the production area, sudden changes can cause dimensional changes, which may affect the accuracy of the blister forming process. Allowing the film to rest in the production environment for a few hours can help minimize these effects.
In some cases, the film may need to be pre – treated to improve its adhesion or printing properties. This can involve processes such as corona treatment or surface coating. However, these treatments need to be carefully controlled to ensure that they do not damage the film or affect its performance.
Handling During Forming and Sealing
The forming and sealing processes are the core operations in blister packaging production. Special care should be taken during these processes to ensure high – quality blister packaging.
During the blister forming process, the film is heated to a specific temperature and then formed into the desired shape using a mold. The temperature and pressure settings need to be carefully adjusted according to the type and thickness of the film. Overheating can cause the film to melt or deform, while insufficient heating may result in incomplete forming.
In addition, the mold used for forming should be clean and well – maintained. Any contaminants or scratches on the mold surface can transfer to the film, affecting the appearance and quality of the blister. Regular cleaning and inspection of the mold can help prevent these issues.
Sealing is another crucial step in blister packaging. The sealing temperature, pressure, and time need to be optimized to ensure a strong and reliable seal. Improper sealing can lead to leakage, which can compromise the product’s integrity and shelf life. It is also important to ensure that the sealing area is free from any debris or product residue, as this can interfere with the sealing process.
Handling of Spent or Waste Film
Proper handling of spent or waste film is not only important for environmental reasons but also for safety and cost – efficiency. Spent blister packaging film should be collected and stored separately from other waste materials.
Recycling is an environmentally friendly option for handling waste blister packaging film. However, not all types of film are recyclable, and the recycling process may vary depending on the film’s composition. It is important to work with a reputable recycling company that has the expertise and facilities to handle blister packaging film.
In addition, waste film should be stored in a safe and proper manner to prevent fire hazards. Some types of blister packaging film are flammable, and storing them in a well – ventilated area away from sources of ignition is essential.
Conclusion
In summary, blister packaging film requires special handling at every stage of its life cycle, from storage and transportation to pre – processing, forming, sealing, and waste management. By following the proper handling requirements, businesses can ensure the quality and performance of their blister packaging products, minimize production problems, and reduce costs.
