Shrink films, which are widely used in the packaging and wrapping field, have transverse and longitudinal shrinkage properties after being subjected to heat treatment. Shrinkage rates in both directions are controlled and these rates are provided with appropriate raw material selection and process conditions. Film thickness, inflation rate, thinning rate, raw material(s) used, and temperature and time during shrinking are the basic factors that determine shrink properties.
Shrink Film
Shrink films, which are used in a wide range of widths and thicknesses, are most commonly used in width / thickness ranges of 40 – 100cm / 40 – 90 microns.
The benefits of shrink films, which are generally preferred in the packaging of cardboard boxes, beverages, canned goods, paper packages, etc.:
- It wraps in accordance with the shapeof the product.
- It gives shine to the product it wraps.
- It extends the shelf life and protects the product.
- It enables the transportation of products in bulk.
- Packaging costs are cheap.
Different additives can be used to give the film a different feature for each application, depending on customer demand and intended use.
Advantages of Shrink Film Packaging:
- Reduces packaging volume,
- increases stacking capacity.
- Environmentally friendly due to reduced packaging volume.
- Unlike cardboard packaging that requires adhesives, single component packaging.
- Double packaging performance.
- Resistant to high and low temperatures and UV resistance.
- Resistance to liquids and moisture.
- Good mechanical properties.
