The cast extrusion process is a continuous process in which thermoplastic material is melted and extruded through a flat die onto a cold roll where it is quenched and re-solidified. This process gives cast stretch film excellent clarity, requires operation less force to stretch, is more resistant to tearing,
relaxes quietly from the machine, and provides better adhesion. Both machine-grade and hand-grade cast stretch films are available.
Advantages of cast stretch film – typically less expensive than blown operation stretch film due to reduced manufacturing costs Higher clarity allows the user to see the packaged product. Cast stretch wrap can be unfolded quietly compared to blown stretch wrap.
cast stretch film provides a double-sided lamination that allows the wrapped product to remain firmly wrapped.
Disadvantages of cast stretch film – does not provide the load/holding power that blown stretch film provides. Cast stretch film has operation lower memory and tear resistance than blown stretch film.
Advantages of Cast Stretch Film- Generally less expensive than blown stretch film, due to reduced manufacturing costs. Increased clarity allows users to see wrapped products. Cast stretch wrap unwinds quietly compared to blown stretch wrap.
Cast stretch film offers two sided cling that allows the wrap to stay securely wrapped.
Disadvantages of Cast Stretch Film- Does not offer the load/holding power blown stretch film offers. Cast stretch film has less memory and tear resistance than blown stretch film.
Blown Stretch Wrap- Also referred to as blown stretch wrap, is operation manufactured using the blown extrusion process. This Plastic melt is extruded through an annular slit die, usually vertically, to form a thin walled tube. Air is introduced via a hole in the center of the die to blow up the tube like a balloon.
On top of the tube an air ring operation blows onto the film to cool it. This process allows blown film to be tougher and more resilient than cast film. The higher mechanical properties of blown film typically allow a greater load holding power.
It’s been two years, but our podcast on the journey of building a brewery business is back for a third season! The first season was about how we built our first brewery and the second season was about our efforts in quality and submitting for the AIBA Beer Awards.
This season is all about growth. Co-founder Dan will host this season operation and will interview key Black Hops employees and other brewery owners to help breweries understand the challenges of growing a brewery brand.
