Shrink wrapping is a very popular way to protect and package items. You often see it on DVD box sets, books, and other products. They are also handy for wrapping food in the kitchen. Different industries use shrink wrapping for a variety of reasons.

However, there are some pros and cons that you should be aware of when it comes to shrink wrapping. It&#;s important to know the pros and cons so that you can make an informed decision on whether or not it is suitable for your business or product. This article will give you a good overview of the advantages and disadvantages of shrink wrapping.

Advantages of Shrink Wrapping

Depending on the industry, shrink wrapping plays an important role in the production, shipping, and sales process. In the past, shrink wraps were used to protect products from tampering and damage. They often protect glass bottles, cans, and other types of containers that could break easily.

With innovation and technology, shrink wraps are used in many different industries and for various purposes. Some common applications and industries that use shrink wrapping are:

Food and Beverage Industry

The food and beverage industry is one of the biggest users of shrink wrap. It plays a crucial role in keeping food sanitary and fresh. Shrink wrap can also provide tamper evidence for products like milk and juices.

Pharmaceuticals, Health Care, and Cosmetics Industries

These industries are very similar to the food and beverage industry. They both require a high level of hygiene and safety. Shrink wrap is used on bottles that contain medicine or cosmetics and bandages, gauze pads, etc.

Entertainment Industry

Another popular industry is the entertainment industry. It&#;s a widely known fact that packaging plays an important role in sales, especially for DVDs, games, and music albums. A good-looking package can also help increase brand image or recognition among consumers. You can use shrink wrap to add that extra layer of protection and make the product look more appealing.

Electronics Industry

The electronics industry is one of the most high-tech industries in the world. It&#;s no wonder that they use shrink wrap to protect their products during shipping. Shrink wrap helps keep out moisture from the air, which can cause electronic products to malfunction.

Construction Industry

The construction industry is constantly changing as new materials develop. Shrink wrap helps protect building supplies from these outdoor elements. These industrial shrink wraps are often custom-made to fit the specific product.

Disadvantages of Shrink Wrapping

While shrink wrapping does have some benefits, it also has a few disadvantages that you need to know before use.

Environmental Impact

The main disadvantage of shrink wrap is its negative environmental impact. It takes a lot of energy and resources to produce and ship the shrink wrap products. If you are a business owner, this can be a big part of your carbon footprint and something you must consider.

Cost

Unlike cardboard boxes or paper packaging, shrink wraps cost more money to produce, ship, and store. You also have to factor in the cost of buying a shrink wrap machine if you intend to create your own shrink wrap instead. These machines can range from $200 to $ depending on their size and quality.

Storage Space

Shrink wraps take up a lot of storage space, which can be an issue for businesses that are tight on space. If you have limited warehouse or shelf space, then you may want to consider other packaging options.

Labor

Shrink wrap also requires a lot of manual labor to apply and remove from the product. This can be a disadvantage if you are looking for an automated process.

Final Thoughts

Weigh the pros and cons before deciding whether shrink wrap is right for you and your business. It&#;s a great option to protect your products and keep them sanitary, but it can also be costly and take up valuable storage space. Consider all the advantages and disadvantages of shrink wrapping to help you decide the best packaging solution for your business.

Pros and Cons of Heat Shrink Wrapping

Heat shrink wrap, also known as heat shrink film, is one of the most popular shrink packaging materials used in the world. As the name suggests, the packaging material shrinks around the product when exposed to heat and provides a layer of protection during transit and storage.

Advantages of heat shrink wrapping

Made of polymer plastic film, heat shrink wrap is available in a variety of thicknesses, clarities, strengths and shrink- ratios. Each type can be used as standalone packing material or in combination with another heat shrink wrap material type to create the required layering and protection for the product.

Once the plastic film is wrapped around the product, it is exposed to heat using a conveyor heat tunnel or an electric or gas heat gun which shrinks the plastic around the product and seals it. Heat shrink wrap can be recycled and remade for future uses.

Heat shrink wraps are being widely used for the following:

  • Primary packaging solution in the manufacturing industry
  • Protection of large machinery that is not in use
  • Marine shrink wrapping of boats and other vehicles
  • Scaffold wrap containment of buildings
  • To quarantine entire buildings where hazardous chemicals or materials may have been exposed
  • Packing palletized freight and securing boxes
  • To advertise products and brands, as heat shrink wraps are printable

Disadvantages of heat shrink wrapping

The three main types of films used in heat shrink wrapping are polyvinyl chloride (PVC), polyolefin (POF) and polyethylene (PE). They come with their fair share of shortcomings such as:

  • PVC softens and wrinkles if the temperature gets too high. And, it becomes hard and brittle if it becomes too cool.
  • On heating, PVC releases strong, harmful odors. Hence, heat shrink wrapping should be done only at well-ventilated locations.
  • Due to the chemical composition and harmful by-products of PVC, many countries have banned its use.
  • Polyolefin is expensive compared to PVC film. Also, it may require perforations in some applications to avoid air pockets or bumpy surfaces.
  • Polyethylene has a low shrink rate of around 20% and is not as clear as other films. Plus, it is more expensive than other films.

Common Problems of Heat Shrink Wrapping

Heat shrink wrapping is cost-effective and space-saving; however, it is not a foolproof packaging solution.  Most common problems arise from improper handling of heat shrink wraps or heating devices. Simple solutions for heat shrink wrapping problems include using the heating device at the right temperature, conveyor speed, air velocity of the tunnel or something as basic as choosing the right heat shrink wrapping film depending on the use.

Problems heat shrink wrapping display include:

Dog Ears

Resembling a dog&#;s ear, these are the triangular protrusions of the film on the corners of a package. They occur due to insufficient shrinkage of the film, causing the corners to not shrink enough. It can be avoided by applying more heat to the shrink film or by using high-quality films.

Ballooning

Heat shrink wrap ballooning happens when the shrink film is exposed to hot air after sealing. The air inside the wrap expands and causes the film to balloon. This can be solved by using film with vent holes, also known as a pre-perforated film, which allows air to escape as the film shrinks around the product.

Burn Holes

Burn holes occur when too much heat is applied to the shrink film. It can be easily avoided by ensuring that the film is exposed to the right temperature while sealing.

Fish Eyes

Fish eyes are round or oval patterns that arise in the plastic due to insufficient shrinking caused by a lack of heat or bad air velocity. Proper maintenance of the heating element can solve this problem.

Shrink Film Tears

Tears in heat shrink film are often caused by the type of shrink film or the thickness of the film being used. Switching to a different kind of film would fix this heat shrink wrapping problem.

In Conclusion

Heat shrink wrapping is an easy way to ensure your products are safe. It offers many types of flexible packaging film options to ensure complete protection of your product. Be it robustness or recyclability and sustainability, there is a heat shrink film to match every business needs.
