Breeding bag

摘要

The breeding sac (1) comprises walls (2), in which a wall region (3) permeable for oxygen and carbon dioxide is formed with a layer made of a micro-porous foil (5) in a multi-layered manner. The walls are made of plastic foils. The micro-porous foil is tearably formed in a spliced manner, locks as outer layer with the breeding sac, is equipped with a tear thread or opening aid, is provided with a break line for breaking, is closed with a tearable tight edge seam (6, 8) in a region-wise manner and projects with a grip section over the edge seam.

The walls are made of plastic foils. The micro-porous foil is tearably formed in a spliced manner, locks as outer layer with the breeding sac, is equipped with a tear thread or opening aid, is provided with a break line for breaking, is closed with a tearable tight edge seam (6, 8) in a region-wise manner and projects with a grip section over the edge seam. The outer layer made of the micro-porous foil is arranged to a further layer made of micro-porous foil, where the further layer is tearably formed and has larger pores than the outer layer. The outer layer and the further layer are applied on a continuous but perforated foil region of the sac wall. The micro-porous foil consists of chalk-filled and high-stretched polyolefin foil, non-woven or non-oven-like structure, and fine-perforated or perforated plastic foil.
