Abstract

bolsa flexível. a presente divulgação fornece uma bolsa flexível. em uma modalidade, a bolsa flexível inclui uma estrutura de primeira camada e uma estrutura de segunda camada. cada estrutura de camada inclui (i) um forro interno e (ii) uma bainha externa. a estrutura da primeira camada é sobreposta à estrutura da segunda camada de modo que os forros internos se oponham. a estrutura da primeira camada sobreposta à estrutura da segunda camada define uma borda periférica comum. cada forro interno é composto por um filme flexível de material polimérico. cada bainha externa é composta por um material polimérico de reciclagem pós-consumo (pcr). o material de polímero de pcr tem um valor gi200 superior a 50. a bolsa flexível inclui uma vedação periférica. a vedação periférica se estende ao longo de pelo menos uma porção da borda periférica comum. a vedação periférica veda a estrutura da primeira camada à estrutura da segunda camada.
