摘要
The invention relates generally to the field of plastics manufacturing. In particular, but not by way of limitation, the invention relates to a system and method for manufacturing co-extruded plastic film and products using same. In one embodiment, a first plastic layer having a relatively high melting temperature is co-extruded with a second plastic layer having a relatively low melting temperature. Embodiments of the invention also disclose manufacturing processes for end products that exploit the improved co-extruded film. One embodiment is a process for manufacturing a bag stack with releasable bonds between adjacent bags in the bag stack. Another embodiment is a process for manufacturing a stack of plastic sheets with releasable bonds between adjacent sheets in the sheet stack.
