The transparent film three-dimensional packaging machine has high requirements for the tensile performance adaptation of packaging films. It needs to meet the requirements of film stretching, forming and heat sealing during the packaging process of the equipment. The specific adaptation points are as follows:
The tensile performance meets the requirements
Tensile strength: The packaging film must have sufficient tensile strength to withstand the tensile force during the packaging process without breaking. If the tensile strength of the film is insufficient, it may break during the packaging process, affecting the packaging effect and efficiency.
Elongation at break: An appropriate elongation at break allows the film to undergo a certain degree of deformation during the stretching process without breaking, which helps the film closely adhere to the shape of the product and achieve a good packaging effect. If the elongation at break is too low, the film may not be able to adapt to the shape changes of the product, resulting in loose packaging.
Elastic recovery rate: A good elastic recovery rate enables the film to quickly return to its original shape after being stretched, maintaining the stability and aesthetic appeal of the packaging. If the elastic recovery rate is poor, the film may not fully recover after being stretched, resulting in loose packaging.
Self-adhesiveness: Although self-adhesiveness is not a necessary characteristic for all packaging films, for some packaging requirements that need a tight fit, a certain degree of self-adhesiveness can help the film better wrap the product, reducing loosening and displacement during the packaging process.
The influence of tensile properties on packaging
Packaging tightness: Appropriate tensile properties enable the film to closely adhere to the product, preventing it from loosening or getting damaged during transportation and storage.
Packaging efficiency: Good tensile properties help increase packaging speed and reduce packaging interruption and adjustment time caused by film breakage or relaxation.
Packaging cost: Suitable tensile properties can reduce the waste of film and lower packaging costs. If the tensile properties of the film are too strong or too weak, it may lead to excessive use or waste of the film.
