Orientated Polypropylene (OPP)
OPP is a resource efficient and cost effective material, however opening of packs can be difficult.
Ultimate Packaging has worked with its suppliers to develop an easy open alternative that can be used in place of a standard OPP films without capital expenditure or engineering time adapting packing lines.
The easy open function is achieved by adding peel technology to the seals. The heat sealing range of the film remain wide, with good heat seal performance between 110 ⁰C – 170 ⁰C at 2.5 bar with a 300 ms dwell and 300 ms cool time
Slip properties of the film remain in line with standard OPP films with the specification reflecting standard OPP values and measurement matched up with current OPP films used.
Other mechanical and optical values remain comparable to standard OPP films and requiring no compromises to performance to reach potential new consumers.
When trialled on packing equipment the product ran well with no adjustments required. The packs provided easy open without the complication of adjusting setting or the requirement for capital expenditure.
