Plastic films and sheets are evaluated for their quality standards depending the area of applications. The materials for films include PE, PET, PA, PS, PMMA, PC, ABS, PVC, PEEK, PEI, PES, PVDF. PMP, PSD, ECTFE and used in packaging industry, food, backing, chocolates, medical, pharma, automotives, stationery, printing, furnishing and civil, surface protection, transportations. Maeon Laboratories provide extensive test facility for the Plastic films and sheets.
Thin plastic materials of less than 1.0 mm are used for great number of applications like for packing, lamination, plastic garbage bags, sandwich bags, food containers, tapes and many more. When subjected to tensile testing, we could measure the Elongation, tensile yield strength, tensile modulus and tensile strength at break. Maeon laboratories have requisite facility for conducting Plastic film tensile testing / Polymeric films tensile testing.
Graves tear test for films measure the force to initiate tearing in plastic films, The punched out specimens are subjected to tension load at a constant rate and the load to failure is recorded.
Elmendorf tear testing determines force to propagate tearing through a specified length of plastic film. This facility is available at Maeon laboratories for performing Elmendorf tear testing of Plastic films.
Force necessary to propagate a tear is plastic film and application of tensile force is measured. This facility is available at Maeon laboratories for performing Elmendorf tear testing of Plastic films.

Films Testing II
Plastic films are tested for its resistance to snagging ie dynamic puncture and propagation of that puncture resulting in a tear, by measuring the force required.
Composite films of flexible materials such as cellulose, paper, plastic film, and foil are tested for bond strength or ply adhesion. Maeon Laboratory has facility for Adhesion of film laminates.

Adhesion / Bond strength of film composites
Adhesion Testing of film, Peel testing of films
Adhesive tapes, coated film etc. adhesion of the coating to be as per norms. Maeon Laboratories conduct three types of adhesion peel tests . These test methods cover the measurement of the peel adhesion of pressure-sensitive tapes. .1ST method gives a measure of the adherence, when peeled at 180° angle, to a standard steel panel or to other surface of interest for a single-coated tape. .2nd method gives a measure of the adherence to the backing of a single-coated tape. .3rd method gives a measure of the adherence of double-coated tape to a standard steel panel or other surface of interest.
Peel strength of films, adhesive tapes
Impact testing of Films
Free falling dart impact testing is done for Plastic films – It determines the energy that causes plastic film to fail under specified conditions of impact of a free-falling dart.
Impact Resistance - Free Falling dart Method
ASTM D1709 ISO 7765-1 IS 2508
Coefficient of friction – of films
The friction coefficient test is conducted to the resistance of one material to slide over another or same material. Static coefficient of friction determines the energy required to star the motion between two surfaces. The Kinetic coefficient of friction determine the resistance to sliding once one surface is in relative motion to the another surface. Maeon laboratory carry out this important property on many polymeric and other materials including films.
Coefficient of Friction
ASTM D1894 ISO 8295 IS 13360 P11 S1 IS 2508
The plastic film and various kinds of tape are tested for its resistance level to flammability. The procedure performed for films is vertical burning method, which Maeon laboratory is providing excellent services for the Burning rate determination test.
ASTM D3801 ASTM D4804
Films and tapes are used for numerous electrical applications where electrical resistance , dielectric strength properties are essential. Maeon Laboratories conduct various electrical property tests for films and tapes.
Polymeric Films, adhesive tapes either opaque or transparent require optical property to be controlled for its end application. Maeon Laboratory follow National and International standards to determine properties such as, haze , luminous transmittance, gloss, reflectance and provide valuable data to the customer
