The film impact testing machine, through the hemispherical punch at a certain speed, impacts and passes through the film sample, measures the energy consumed by the punch, and evaluates the anti-pendulum impact energy of the film sample.

The sample to be measured is placed in the middle of two splints to clamp, and the pendulum is adjusted by counterweight to form enough mechanical energy to impact the surface of the sample to be measured during the impact process to break down or not break down the sample to be measured. The energy borne by the sample to be measured is the loss part of the total mechanical energy formed by the pendulum during the impact process, and is read out on the dial through the pointer.

Applications

(1)Packaging Materials

Test the impact resistance of plastic films, laminates, and flexible packaging materials.

Evaluate durability for bags, pouches, wraps, and protective films.

(2)Plastic & Polymer Films

Assess brittleness, toughness, and impact strength of PVC, PE, PET, and other polymer films.

Ensure materials meet quality and safety standards.

(3)Industrial Films & Coatings

Evaluate surface coatings, laminates, and protective films for mechanical stress tolerance.

Determine suitability for automotive, electronics, or construction applications.

(4)Research & Development

Used in laboratories and universities for materials testing, formulation optimization, and durability studies.

Supports R&D of new polymer blends, laminates, and film products.

(5)Quality Control & Production Monitoring

Ensures film materials meet industry or customer specifications before shipment.

Helps identify manufacturing defects and improve production consistency.

(6)Standards Compliance

Supports testing according to ASTM, ISO, and other international standards for film impact resistance.

Accessories

(1)Dart (Impact Head)

A hemispherical impact head used to strike the film specimen.

(2)Weight Set

Used to adjust the total impact mass to meet different test standards.

(3)Specimen Clamping Device

Holds the film securely to prevent movement during testing.

(4)Guide Tube (Drop Tube)

Ensures the dart falls vertically and impacts the correct position.

(5)Release Mechanism

Controls the accurate release of the dart from a specified height.
