10 Jun What is shrink wrap?
Shrink wrap is a packaging material made from a polymer plastic film that is wrapped around a product and tightened by applying heat to create a seal. The resulting package is airtight, moisture-proof, and tamper-resistant. Shrink wrap is widely used in industries like food, electronics, cosmetics, pharmaceuticals, and many more that require protection, preservation, and branding of their products.
Shrink wrap comes in two types: PVC and Polyolefin. PVC (Polyvinyl Chloride) is a more economical and commonly used shrink wrap film and is best for heavier and bigger products. The PVC shrink wrap has a strong resistance to tearing and puncture, and it’s an excellent barrier against moisture. On the downside, PVC shrinks unevenly, making it less desirable for smooth and soft products. In contrast, Polyolefin shrink wrap is more expensive and known for its softer and smooth finish. It is commonly used in applications where high clarity, printability, or easy-opening is required. Polyolefin is FDA approved, which means it’s safe to use with food, and it shrinks evenly, making it an ideal shrink wrap choice for personal hygiene products and pharmaceuticals.
The process of shrink wrapping is straightforward. First, the product is placed inside the shrink wrap film, and then the film is sealed with a heat sealer machine. After the sealing, the package is sent into a shrink tunnel or heat gun to shrink the film tightly around the product. The heat applied also activates the adhesive lining inside the film to create a secure seal. Shrink wrap can be applied to different shapes and sizes of products, making it versatile and flexible in packaging options.
Shrink wrap has many benefits to offer to businesses and consumers. For businesses, shrink wrap adds a layer of protection to their products by keeping them from contamination and damage during shipping and handling. It also provides branding opportunities by having the product’s label printed on the film. Shrink wrap is eco-friendly as it requires less plastic to create the packaging and is widely recyclable. From a consumer standpoint, shrink wrap is easy to use and store, and it keeps the product fresh and new for longer.
In conclusion, shrink wrap is a packaging solution that provides protection, branding, and sustainability benefits for businesses and convenience and freshness for consumers. With its ease of application, versatility, and cost-effectiveness, it has become a popular packaging material in various industries worldwide. Choosing the right type of shrink wrap for a particular product ensures the best packaging solution that will meet the needs of both businesses and consumers.
