AI Technical Summary

Benefits of technology

This new type of plastic films are stronger than regular ones while still being flexible enough that they will be easy to bend or fold up without losing their shape over time. They have better resistance against impact from external factors like rain water, snow, dirt particles, etc., making them ideal for protection during storage and transport before sale. Additionally, these plasties contain no harmful chemical substances such as pesticides used by people working at home remediation facilities. These technical benefits make it more durable and safe compared to older methods of wrapping items together.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the durability and resistance against environmental factors like temperature changes during storage or usage time without compromising on their effectiveness at maintaining good quality product performance.
