Want to understand to what easy peel film is revaluation packaging industries as well as sustainability. We will cover in this article about easy peel film, application, process, market segment, etc.
Introduction
Peelable films are trending in packaging industry, providing convenience and functionality that consumer and supplier appreciate. This film has been made in such a way that when the consumer opens their packaging, the film opens easily without damaging the product. This film has many types of advanced customizable solutions to grow. In this article we will explore about science of easy peel, consumer behavior, structure, material manufacturing process, and their application
What is (Peelable film) easy peel film?
Easy peel film is a specially designed film that opens easily without damaging the product. This film is widely used in food, pharmaceuticals, and Cosmetic industries. The purpose of this film is to allow the consumer to separate the product from the packaging without using scissors or any tool.
Science of Easy peel films
Material composition
Easy peel films are basically divided into three categories.
- Sealant layer (Must be in easy peel combination) of Polyethylene, Polypropylene, Ethylene vinyl acetate (EVA).
2. Barrier layer (This is optional layer in easy peel as required)
3. Structural layer (This layer is also provided to strength, Printing, Instruction and stiffness.)
Importance of easy peel film in packaging?
Now this time everyone wants to dust free products so that easy peel provided a better solution with customizable option.
Convenience
This film makes the consumer feel comfortable opening the packaging.
Extended shelf life
Easy film protects the product from sunlight, moisture, and dust, which increases the product’s shelf life. In the market, there is an easy peel available with a foil base that increases the shelf life of the product.
Protection of product
During transportation, this film product is exposed to dust, damage, and maintain hygiene.
Bonding
This film works on the bonding between the bonding substrate and the base film.
Manufacturing process
Material selection:
Frist off all decide layer of film and structure of film is 2 ply or 3 ply.
Lamination:
All layers will be combined in dry lamination process in solvent base or solvent less machine with help of adhesive and hardener.
Curing:
Curing is a such process where we keep the laminate material at least 24 hrs. in specific temperature to cure the bond strength between layers. Ensure the proper bonding between the layer is required as application of film.
Cutting & Slitting:
When curing of laminate material is complete. Then we can slit in desire size as requirement of Customer.
Application of Easy peel films (Peelable film)
Dairy item: (e.g., Yogurt cups, cheese pack), Ready Meals, Fish & Meat packaging with vacuum seal, Lidding films for PP, Pet, Aluminum trays, personal care items, pharmaceutical industries.
Quality Testing Parameter
Peel strength Test:
ASTM F88 is standard for check the peel strength of peelable film in U.T.M (Universal testing machine). Generally, peel strength is lie between 1.5 -5 N/ 15 mm
Film thickness
A.S.T.M D 6988 is standard for the check the thickness of film with the help of the digital micrometer.
Tensile strength & Elongation
A.S.T.M D 882 is the standard for check the tensile strength & elongation of film. The unit will be in N/mm2 or kg/cm2.
Barrier properties (If applicable)
WVTR (Water vapors transmission rate): ASTM F1249.
OTR (Oxygen transmission rate): ASTM F 3985.
Future trends
Easy peel film is launching like sustainable packaging; easy peel film reduces food waste and extended the shelf life of product. Now mostly industries are developing mono material in peelable film, which is easy in the recycling process. Peelable film is representing premium quality of product protection and ecofriendly for environment.
