Product catalog summary
Introduction
Various types of shrink films, such as PE and POF, are used in packaging to ensure optimal product protection. The performance of these films is critical, as poor shrinkage can lead to packaging issues.

Test Methods Overview
The document compares three primary methods for testing shrink film performance: oil bath, drying oven, and air heating.

Oil Bath Method
This method involves submerging the film sample in hot oil to measure shrinkage. It is not suitable for assessing shrinking or contracting force.

Drying Oven Method
Similar to the oil bath, this method uses an oven to heat the film sample. It measures shrinkage but not shrinking or contracting force.

Air Heating Method
This method heats the film with hot air, allowing for the measurement of shrinkage rate, shrinking force, and contracting force. It provides automated and real-time force display but may yield results that are not comparable with other methods.

Choosing the Right Method
Selection depends on material quality, product standards, and testing purposes. Air heating is recommended for high-efficiency and automatic testing.

Conclusion
Choosing the appropriate test method is crucial for ensuring effective packaging. Labthink offers a variety of testing equipment and encourages industry collaboration for quality control.

A Comparison of Oil Bath, Drying Oven, and Air Heating Shrink Film Test Methods-1

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 A Comparison of Oil Bath, Drying Oven, and Air Heating Shrink Film Test Methods Many shrink film types exist (PE, POF, etc.) used for packaging a wide variety of products. Different products require films with specific shrink performance (shrink rate, shrinking force, contracting force) for optimal packaging. Poor shrink performance can lead to loose or crushed products. The most widely used test methods measuring shrink performance are oil bath, drying oven, and air heating. Oil Bath Method Film sample is submerged in hot oil (e.g., silicone oil) at a set temperature. Sample size is measured before and after submersion to determine shrinkage ratio. Not ideal for measuring shrinking or contracting force. Labthink RSY-R2 Film Free Shrink Tester

Labthink Instruments Co., Ltd. [email protected] +86-531-85068566 Drying Oven Method Film sample is placed in an oven at a set temperature for a set time. Sample size is measured before and after heating to determine shrinkage ratio. Similar to oil bath method, cannot measure shrinking or contracting force. Air Heating Method Film sample is heated by hot air inside a chamber. Measures shrinkage rate, shrinking force, and contracting force. Offers automated measurement and real-time force display. Heating environment differs from other methods, so results may not be comparable. Labthink C631H...
