Stretch film is a very effective method of protecting palletized products through storage and distribution. For more than 20 years, LLDPE resins have provided the best balance of properties to meet the demanding requirements of stretch film applications, with higher alpha olefin co-monomer grades being the clear market and technology leaders.
As film converters continuously strive for more cost effective production and packaging applications become more demanding, using high speed and/or high pre-stretch machines, the structure of these films is changing. The core layers are based on high performance higher alpha-olefin polymers and are increasingly made from metallocene based resins.
The Dow Chemical Company (Dow) plastics provide many benefits, notably stretchability, holding force and resistance to tears and punctures.
