Cool invention! A crusher is a great thing even on a production scale. Personally, I also started to deal with polyethylene. In cases where the main products for processing are polyethylene products (films, bags) and PET (containers, bottles, any container), it is reasonable to buy a crusher with V–shaped knives. The design of the machine is optimized for shredding thin-walled waste and films, knives cut plastic on the principle of scissors. The GV series is represented by models with a capacity from 80 to 800 kg/hour. You can find it using https://www.amazon.ca/HomeBuddy-Can-Crusher-Recycling-Aluminum/dp/B08D6QV6B5
