A rolled-up mattress is vacuum compressed?
No, it is not. In order to vacuum pack products, we have developed a special double sealing bar system for our packaging machines. The double sealing bars seal the product on all four sides, so that product volume reduction is kept for more than 24 hours. Moreover, a PAPE film (made of polyethylene and nylon) must be used to vacuum-pack. Hence, the combination between our double sealing bars and the PAPE film is the perfect solution to create a resistant, long-lasting final packaging, which keeps product volume reduction. Our double sealing bars are installed on our Pelér, the machine able to pack and vacuum compress PU blocks. Our double sealing bars can be integrated on our Mistral 3B MT + Press and Mistral 3B MCL, packaging machines designed for the mattress and polyurethane industries.
