TPU film easy to recycle? Is it environmentally friendly?

10-05, 2023 | View:

As the importance of environmental protection becomes increasingly prominent, all walks of life are actively exploring more environmentally friendly production methods and materials. As a polymer material widely used in various fields, TPU film has attracted much attention for its environmental performance. This article will conduct an in-depth discussion on the environmental performance of TPU film, including whether it is easy to recycle, its impact on the environment, and how to use it more environmentally friendly.

1. Difficulty of recycling TPU film

TPU film is a polymer material whose recycling difficulty is relatively higher than that of some traditional plastics such as PE and PP. First of all, the recycling of TPU films requires a relatively complex process, including sorting, crushing, cleaning and drying. Secondly, the utilization methods of TPU film after recycling are relatively limited and can generally only be used to manufacture lower-end products or fillers.

Although the recycling of TPU films is difficult, some advanced recycling technologies can already achieve effective recycling of TPU films. For example, supercritical fluid technology can be used to decompose TPU films into raw materials for recycling and reuse. This technology has higher energy efficiency and lower environmental pollution.

2. Environmental impact of TPU film

As a polymer material, TPU film's impact on the environment during production, use and recycling is also a matter of concern. First of all, the production process of TPU films requires the use of a large amount of fossil energy and chemical raw materials, which not only consumes a large amount of natural resources, but also emits a large amount of waste gas, waste water, waste residue and other pollutants. Secondly, if TPU film is not properly processed and recycled during use, it will become one of the main sources of "white pollution" and have an irreversible impact on the environment.

Although there is certain environmental pressure during the production and use of TPU films, the environmental impact of TPU films can be effectively reduced by adopting more environmentally friendly production technologies and selecting more environmentally friendly raw materials. For example, biodegradable materials can be used to replace some TPU raw materials to produce a more environmentally friendly TPU film.
