The Ultimate Guide to Interpret Technical Terms on PE Shrink Film

To understand any process or product, you first of all need to understand all of its technical terms related to it. Similarly, when dealing with packaging material, you need to be thorough with related words, their properties, and their exceptions. With deep experience and business in PE shrink film, Shree Pragya Flexifilm Industries brings you a wide array of technical terminologies that will help you interpret technical definitions on PE shrink films.  

PE Shrink Film: An Overview 

A PE shrink film that wraps efficiently around the product when exposed to a specific amount of heat. This helps in securing a range of products such as packs of beverages, cans, toys, electronics, etc. It offers many advantages over traditional packaging, and it is cost-effective, durable, waterproof, and also environmentally friendly. The effectiveness of shrink film primarily depends upon the raw materials and the refining process. Purchase the most premium quality of the PE shrinkage film from Shree Pragya Flexi Films. We are a leading PE shrink film manufacturer and process them under strict quality control.  Our products can be customised according to thickness, printability, and length, and are also treated with UV stabilisers.

Terminologies Related to PE Shrink Film

1. Gloss: Gloss, as the word suggests, is the measurement of the light reflected off the film surface at a given angle. The most usual angle used to measure the glossiness of a sheet is 45 degrees. The higher this number, the glossier the sheet. 
2. Haze: Haze is the amount of cloudiness present in the sheet at the end of processing. While manufacturing, it is ensured that the haze number is as low as possible. Low haze amount advocates for the premium quality of film. 
3. COF:  COF stands for the coefficient of friction. It measures whether the film can slide on itself or on another surface. This coefficient is necessary to understand, as different purposes require different levels of COF. Some may require the sheet to be slippery, whereas some may require it to be rigid. 
4. Shrinkage MD/TD: Also known as unrestricted shrink, is the amount of shrink measured in two directions: Machine direction (MD) and cross-section (TD). 
5. Tear Resistance MD/TD: It is the ability of the film to resist tearing due to force and friction. It is measured in both directions of the machine and the transverse section. High-clarity films have a higher resistance to tears. 
6. Ultimate Tensile MD/TD: Tensile strength stands for the total amount of pressure or force the film can withstand. 
7. MVTR: It stands for moisture vapour transmission rate, for the amount of moisture passed through the film. The number of MTVRs must be low to ensure low moisture transmission. 
8. Elongation MD/TD: It measures the percentage of a film that will distort or stretch before breaking. This number must be high to ensure it resists tearing and cracking. 
9. Modulus: It measures the stiffness of the film. These numbers must be lower to ensure the sheet is softer. 
10. OTR: The oxygen transmission rate measures the amount of oxygen through the film. The amount of the oxygen transmission rate must be lower in packaging items which don’t require oxygen and must be higher for items which does require oxygen.

How To Use This Information 

Use these terms to analyse the requirements of the product. Each of these terms can be used to ensure that you use the correct type of film for the specific application. By having accurate knowledge of the terminologies, you can reduce the wastage of material, improper tearing, improper shrinkage, etc. It can also help you to find the right type of gauge, type, tool and width of shrink film. This can help in identifying the correct type of shrink film for your products and packaging.
