Blown Stretch Film Mechanical Properties Test

Blown stretch film plays a crucial role in packaging, ensuring product stability and protection during transportation and storage. To maintain consistent quality, the blown stretch film mechanical properties test is essential. This article outlines the key test purposes, procedures, and application materials involved in mechanical property testing for stretch films, supporting optimal performance in various industries.

Blown Stretch Film Mechanical Properties Test – Puncture Test

그만큼 펑크 테스트 evaluates the resistance of blown stretch film to penetration from sharp objects. This is critical in assessing how well the film protects packaged goods under stress or during handling. It involves using a standardized probe to apply force until the film is pierced, recording the force at break and the energy absorbed.

Cell Instruments’ TST-01 Film Puncture Tester provides precise control and data output for evaluating puncture performance in compliance with ASTM D5748.

Blown Stretch Film Mechanical Properties Test – Peel Cling Test

그만큼 peel cling test measures the adhesion between film layers when wrapped. High cling helps maintain film tension and wrap integrity, especially during transportation. This test involves peeling two layers apart at a specific angle and speed, quantifying the required force.

Peel cling properties are critical for film stability, and Cell Instruments offers an automated SPC-01 필 클링 테스터 ensuring accurate force control and real-time analysis, which complies with ASTM D5458.

Blown Stretch Film Mechanical Properties Test – Tensile Strength Test

그만큼 tensile strength test is one of the most fundamental assessments in the blown stretch film mechanical properties test. It determines the maximum stress the film can withstand when stretched. High tensile strength indicates better load retention and resistance to breakage under tension.

This test is performed using a universal tensile tester, such as Cell Instruments’ TST-01 Tensile Tester, ideal for blown stretch films in compliance with ASTM D882.

Blown Stretch Film Mechanical Properties Test – Elongation Test

Often paired with tensile testing, the elongation test measures how much the film can stretch before breaking. This property ensures the film can wrap tightly around irregular loads without tearing. Elongation data helps optimize film formulations for specific load profiles.

Blown Stretch Film Mechanical Properties Test – Elmendorf Tear Test

그만큼 Elmendorf tear test assesses how resistant the film is to tearing once a small nick or cut has formed. It is especially relevant for packaging materials that undergo frequent handling or exposure to sharp edges.

Cell Instruments’ 엘멘도르프 인열 시험기 complies with ASTM D1922, ensuring standardized tear resistance evaluations for packaging films.

Blown Stretch Film Mechanical Properties Test – Impact Resistance Test

그만큼 impact resistance test simulates sudden shocks the film may encounter during handling or transport. By dropping a weight from a specified height, the test measures the energy required to rupture the film, reflecting its toughness under dynamic loads.

Other Test – Thickness Test

그만큼 thickness test ensures consistency across the film’s surface. Variations in thickness can lead to weak spots, affecting mechanical performance and protection. Precision thickness gauges from 셀 인스트루먼트 provide micrometer-level accuracy, supporting consistent production quality.

Application Materials and Industry Relevance

The test applies to a wide range of materials including LLDPE, LDPE, and multilayer stretch films. These are used extensively in the packaging, logistics, food, pharmaceutical, electronics, and beverage industries. Quality control professionals and product developers rely on mechanical property data to ensure reliable film performance in demanding applications.
