6 Most Useful Tips to Buy PVC Shrink Film

Oct. 16, 2023

PVC shrink film is a commonly used packaging material due to its versatility and cost-effectiveness. Whether you are a small business owner or a large manufacturer, buying PVC shrink film can be a daunting task considering the vast options available in the market. To help you make an informed decision, here are six useful tips to consider when buying PVC shrink film.


Determine the Thickness:

The thickness of PVC shrink film plays a crucial role in its durability and functionality. Thicker films are generally more robust and offer better protection to the packaged items. On the other hand, thinner films are more flexible and suitable for irregularly shaped objects. It is essential to assess the requirements of your product and select the appropriate thickness accordingly. Generally, PVC shrink films range from 40 to 100 gauge, with 60 to 75 gauge being the most commonly used thickness for general packaging purposes.

Consider the Shrink Ratio:

Shrink ratio refers to the percentage of shrinkage that PVC film undergoes when heated. It is vital to select a film with an appropriate shrink ratio to ensure that it can tightly conform to the shape of the product being packaged. Most PVC shrink films have a shrink ratio between 40% and 50%. However, it is essential to consider the nature of your product and its potential reaction to heat. Delicate or heat-sensitive items might require a lower shrink ratio to avoid any damage during the packaging process.


Evaluate the Clarity:

Clarity is an important factor to consider when buying PVC shrink film, as it directly affects the visibility of the packaged item. High clarity films allow the product to be clearly seen, enhancing its aesthetic appeal. On the other hand, low clarity films can make the product appear foggy or dull. If you are packaging products that need to be visually appealing, such as food items or cosmetics, it is recommended to opt for PVC shrink film with excellent clarity. However, if the appearance is not a significant concern, lower clarity films can be a cost-effective option.

Check for Chemical Resistance:

If you are packaging products that might come in contact with chemicals or oils, it is crucial to select PVC shrink film that offers good chemical resistance. Certain chemicals can react with the film, leading to discoloration, degradation, or loss of shrinkage properties. To avoid potential issues, make sure to choose PVC shrink film that is specifically designed to withstand the chemicals or substances present in your product.


Consider the Printing Compatibility:

If you plan to print on the PVC shrink film for branding or labeling purposes, it is essential to check its printing compatibility. Some films are specifically designed for high-quality printing results, while others might not adhere ink properly or provide satisfactory print clarity. Therefore, it is advisable to consult with the film supplier or manufacturer to ensure that the chosen film is suitable for your printing requirements.


Assess Environmental Impact:

In recent years, there has been an increased focus on sustainability and environmental impact. It is essential to consider the environmental implications of PVC shrink film before making a purchase. PVC is not a biodegradable material, and its production process involves the use of harmful chemicals. However, there are PVC shrink films available in the market that are formulated with eco-friendly additives or are produced using more sustainable practices. If sustainability is a critical factor for your business, opt for PVC shrink film that has been specifically labeled as eco-friendly or explore alternative packaging materials.


In conclusion, buying PVC shrink film requires careful consideration of factors such as thickness, shrink ratio, clarity, chemical resistance, printing compatibility, and environmental impact. By keeping these tips in mind, you can make an informed decision and select the right PVC shrink film for your packaging needs.
