Introduction

Blister and strip packaging are two popular methods used in the pharmaceutical and consumer goods industries to package products. Both methods have their own set of attributes that make them suitable for different types of products. In this article, we will compare the attributes of blister and strip packaging to help you understand the differences between the two.

Material

Blister packaging typically consists of a pre-formed plastic cavity that holds the product securely in place. The plastic used in blister packaging is usually PVC, PET, or PP. On the other hand, strip packaging involves sealing the product between two layers of plastic film. The plastic film used in strip packaging is usually made of materials like PVC, PVDC, or aluminum foil. Both blister and strip packaging provide excellent barrier properties to protect the product from moisture, light, and oxygen.

Visibility

One of the key differences between blister and strip packaging is the visibility of the product. In blister packaging, the product is visible through the transparent plastic cavity, allowing consumers to see the product before making a purchase. This can be particularly important for products that rely on visual appeal to attract customers. On the other hand, strip packaging typically does not offer the same level of visibility, as the product is sealed between two layers of opaque film.

Convenience

When it comes to convenience, blister packaging is often considered more user-friendly than strip packaging. Blister packs are easy to open and reseal, making them ideal for products that need to be accessed multiple times. In contrast, strip packaging can be more difficult to open, especially for elderly or disabled individuals. However, strip packaging is often more compact and lightweight than blister packaging, making it easier to transport and store.

Cost

Cost is another important factor to consider when choosing between blister and strip packaging. Blister packaging tends to be more expensive than strip packaging, as it requires additional materials and machinery to create the pre-formed plastic cavities. On the other hand, strip packaging is a more cost-effective option, as it involves simply sealing the product between two layers of film. This makes strip packaging a popular choice for products with lower profit margins.

Sustainability

As consumers become more environmentally conscious, sustainability has become a key consideration in packaging decisions. Blister packaging is often criticized for its use of non-biodegradable plastics, which can contribute to environmental pollution. Strip packaging, on the other hand, can be made from recyclable materials like aluminum foil or biodegradable plastics. This makes strip packaging a more sustainable option for companies looking to reduce their environmental impact.

Security

Security is another important attribute to consider when choosing between blister and strip packaging. Blister packaging provides a high level of security, as the product is securely held in place within the plastic cavity. This can help prevent tampering and ensure the product reaches the consumer in its original condition. Strip packaging, on the other hand, may be more susceptible to tampering, as the product is simply sealed between two layers of film.

Conclusion

In conclusion, both blister and strip packaging have their own set of attributes that make them suitable for different types of products. Blister packaging offers excellent visibility and security, but can be more expensive and less sustainable than strip packaging. Strip packaging, on the other hand, is more cost-effective and sustainable, but may not offer the same level of visibility and security as blister packaging. Ultimately, the choice between blister and strip packaging will depend on the specific needs of the product and the preferences of the manufacturer.
