Understanding Flexible Film
Understanding Flexible Film
Flexible packaging film a polymer-based material that contracts when exposed to heat, tightly enveloping the item it encases. This reaction results from the material’s unique molecular structure, which changes during the heating process. The film is made of prime grade virgin material, among other materials and it’s remarkable to see how much this seemingly simple material can impact the entire production line.

FILM TYPES & CHARACTERISTICS TERMINOLOGY
FILM TYPES & CHARACTERISTICS TERMINOLOGY
Blown Film -A film extruded by the blown (air inflation) system. Sometimes erroneously called "extruded" film.
Heat Shrinkable Films -Films which have gone through an orientation step in the manufacturing process, which shrink significantly with application of heat, generating a substantial shrink force.
PACKAGING FILM OVERVIEW
PACKAGING FILM OVERVIEW
• Formulated by industry experts for toughness and commercial fit.
• Ideal for rough handling in distribution, like warehouse clubs.
• High shrink energy unitizes items, eliminating need for supporting trays.
• Excellent memory prevents relaxation under fluctuating temperatures.
• Exceptional tensile strength allows use in thinner gauges.
• Produces high-integrity seals over a broad temperature range.
• Runs at excellent speeds on various packaging equipment.
• Outperforms other films in merchandising appeal with excellent optics.
• Provides a premium look to consumer products.
