What materials can be used for blister packing with a Manual Blister Packing Machine?

When it comes to blister packing, a Manual Blister Packing Machine is a versatile and cost - effective solution for many small - to - medium - scale businesses. As a supplier of Manual Blister Packing Machines, I understand the importance of choosing the right materials for optimal performance. In this blog, I will explore the various materials that can be used with a Manual Blister Packing Machine.

1. PVC (Polyvinyl Chloride)

PVC is one of the most commonly used materials in blister packing. It is a thermoplastic polymer that offers several advantages. Firstly, it is highly transparent, which allows consumers to easily see the product inside the blister. This is particularly useful for products such as consumer goods, toys, and small electronics, where the visual appeal of the product is important.

PVC is also relatively easy to form into blisters using a Manual Blister Packing Machine. It has good heat - sealing properties, which means that it can be effectively sealed to a backing card or foil. Additionally, PVC is a cost - effective material, making it a popular choice for businesses looking to keep their packaging costs down.

However, PVC does have some drawbacks. It is not as environmentally friendly as some other materials, as it contains chlorine and can release toxic substances when burned. Also, it has relatively poor barrier properties against moisture and oxygen, which may not be suitable for products that are sensitive to these elements.

2. PET (Polyethylene Terephthalate)

PET is another widely used material in blister packing. It is a strong and lightweight thermoplastic with excellent clarity. Similar to PVC, it allows for a clear view of the product, enhancing its visual appeal.

PET has better barrier properties than PVC, especially against oxygen and moisture. This makes it a great choice for products that require protection from these environmental factors, such as food items, pharmaceuticals, and some high - end consumer products. It is also more environmentally friendly than PVC, as it is recyclable.

When using a Manual Blister Packing Machine, PET can be formed into blisters with relative ease. It has good heat - sealing characteristics, although the sealing process may require slightly different temperature and pressure settings compared to PVC.

3. PP (Polypropylene)

Polypropylene is a tough and flexible thermoplastic material. It is known for its high chemical resistance, which makes it suitable for packaging products that may come into contact with chemicals or solvents. PP also has good heat - resistance properties, which means it can withstand higher temperatures without deforming.

In blister packing, PP offers good protection for products. It has better moisture - barrier properties than PVC, and it is also more environmentally friendly as it is recyclable. When used with a Manual Blister Packing Machine, PP can be formed into blisters with proper heat and pressure application.

However, PP has lower clarity compared to PVC and PET. This may not be a problem for products where the visual display is not the primary concern, such as industrial parts or some types of hardware.

4. Aluminum Foil

Aluminum foil is a popular choice for blister packing, especially in the pharmaceutical and food industries. It has excellent barrier properties against moisture, oxygen, light, and bacteria. This makes it ideal for protecting sensitive products, such as tablets, capsules, and perishable food items.

Aluminum foil can be used as a lidding material in combination with a plastic blister. When sealed to a plastic blister using a Manual Blister Packing Machine, it provides a hermetic seal that keeps the product fresh and protected. It also has good heat - sealing properties, which ensure a strong and reliable seal.

On the downside, aluminum foil is relatively expensive compared to plastic materials. It is also not as flexible as some plastics, which may limit its use in certain applications.

5. Paperboard

Paperboard is a sustainable and cost - effective option for blister packing. It can be used as a backing card for plastic blisters. Paperboard is easy to print on, which allows for branding and product information to be clearly displayed.

It provides some level of protection for the product, although its barrier properties against moisture and oxygen are relatively poor compared to plastic and aluminum materials. However, for products that are not highly sensitive to these elements, such as some consumer goods and promotional items, paperboard can be a suitable choice.

When using a Manual Blister Packing Machine, paperboard can be easily sealed to a plastic blister using adhesives or heat - sealing techniques.

Considerations When Choosing Materials

When selecting materials for blister packing with a Manual Blister Packing Machine, several factors need to be considered.

Product Requirements

The nature of the product is the most important factor. For example, if the product is a pharmaceutical tablet, it will require a material with excellent barrier properties to protect it from moisture, oxygen, and light. On the other hand, if it is a toy or a small consumer item, visual appeal may be more important, and a transparent plastic material like PVC or PET may be a better choice.

Cost

Cost is always a significant consideration for businesses. PVC and paperboard are generally more cost - effective materials, while aluminum foil and some high - performance plastics like PET can be more expensive. Balancing the cost with the required level of protection and visual appeal is crucial.

Environmental Impact

In today's environmentally conscious world, the environmental impact of packaging materials is becoming increasingly important. Materials like PET, PP, and paperboard are more environmentally friendly as they are recyclable, while PVC has a more negative environmental footprint.

Machine Compatibility

Different materials may require different settings on the Manual Blister Packing Machine. For example, the temperature, pressure, and sealing time may need to be adjusted depending on the material being used. It is important to ensure that the chosen material is compatible with the capabilities of the machine.
