How to Control the Strength of Plastic Film During Manufacturing

This test instrument is designed to measure the strength of plastic film when it falls freely. It is a widely accepted test in the packaging industry and is a reliable way to determine the maximum force the film can withstand before it breaks or fails.

How to Control the Strength of Plastic Film During Manufacturing

This test instrument is designed to measure the strength of plastic film when it falls freely. It is a widely accepted test in the packaging industry and is a reliable way to determine the maximum force the film can withstand before it breaks or fails. This can help you record a quality estimate and produce accordingly. The biaxial orientation of the film increases its overall strength, flexibility, and toughness.

Often used for packaging, surface defects can have a negative impact on product freshness and environmental protection. Adhesion strength is the amount of adhesion between two surfaces. Wind is a major factor in plastic damage, and you don't want to replace the plastic film multiple times a year. Plasticized PVCD packaging film has improved thermal stability and lower adhesion to metal surfaces when 2% by weight of epoxidized soybean oil is added as a plasticizer.

Beyond production and manufacturing processes, plastics may need to be inspected to ensure continuous performance levels. Packaging films require control of many performance parameters to ensure consistency during conversion and use of the film. It is possible to expand the material optimization techniques used by film manufacturers to achieve similar levels of thickness reduction and property optimization in thicker sheets and injection-molded products. Cutters cut large rolls of plastic film into narrower rolls, which can inadvertently cause breaks and other imperfections in the film.

Understanding the requirements of the final product, the effect of HDPE PCR on the properties of the film, and the effects of different mixtures of materials on the properties of the film will help determine which blends to use and if the use of HDPE by PCR will meet customer requirements. Make sure you have blow film process audit forms, plastic film test forms, pens or flags to identify sections of the film to be analyzed, and a measuring tape. Thermoforming is a forming method (normally used in medical packaging) in which a plastic film is deformed while being subjected to heat close to its softening temperature. The ideal film for heat sealing has an outer part with a significantly higher sealing temperature than its inner part, and its inner part has a very wide sealing range.

Copolyester is a plastic film composed of polyester with alcohol or glycol additives added to reduce cost. Inverse relationships between film thickness, stabilizer concentration, and stabilizer effectiveness (LDPE and tinuvin 622 films (HALS- + Chimassorb 81 (UVA blend) and Tinuvina 783 (HALS-7 + HALS mix); test with Atlas weather meter). In blown film production, molten plastic enters a matrix, flows around a mandrel, and exits through a ring-shaped opening in the form of a tube. Product tests on bags and films are used to determine variations in film characteristics due to the addition of PCR materials.
