New formulation allows better processing of PE barrier film


Adapa (formerly Schur Flexibles) says it has revised its SkinFresh Top range of films – and now offers SkinFresh Top Expert. The company says it has developed a new formula- tion that allows for im- proved processing. The new range includes transparent, glossy and printable PE-based films – with high barrier – that enclose products tightly but without tension. They can be used for food products of various heights and are also suitable for packaging products with bones. The high-performance


UHMW-PE Fluoropolymer alternative


At Fakuma 2023, Dreyplas showed a number of alternatives to fluoropoly- mers.


Its melt-processable


UHMW-PE can be used for sheet, films, profiles and coatings in applications where low friction and


STRETCH FILM Pallet stabilisation revealed at Powtech


Berry Global showed the latest versions of its stretch hood film and NorDiVent form-fill-seal (FFS) film at the Powtech exhibition in Germany. The new generation of stretch hood film uses up to 30% recyclate – yet manage to maintain stretch perfor-

mance. Berry has done this while retaining seal integrity and tear resistance. The film is aimed at low to medium stretch applications in markets such as beverage, building, and glass. The stretch hoods provide high load stability and waterproofing,


with lower material usage than traditional shrink hooding films, it says. NorDiVent film – which provides a dust- and moisture-free way of filling and packing powdered products – now includes up to 50% recyclate. � www.berryglobal.com

abrasion are critical. Dreyplas uses Mitsui Chemicals products, which are available as pellets, powders and micro pow- ders. Dreyplas continues to offer a range of fluoropoly- mers for those applications. Highly abrasion-resistant


sheets, profiles and hoses are some of the applica- tions of Lubmer pellets, a self-lubricating, high-im- pact grade of UHMW-PE. It has food safety, acoustic and electrical insulation properties. � www.dreyplas.com


MASTERBATCH


Medical- grade anti-


stat formula Masterbatch specialist Ampacet has introduced a new anti-static formula- tion for polyolefin films used in pharmaceutical processes. The company says that


skin films are available in thicknesses of 80-150 microns and seal reliably to PE sealing layers or APET and PP mono films and trays. For material- and resource- saving applications, it has been possible to reduce film thickness further while


maintaining performance. Users can see how the films perform at Adapa’s PackScience centre in Kempten, which demon- strates them on tray sealers and thermoforming machinery. � www.adapa-group.com


ProVital + Permstat is used in the external layers of packaging films to create a dissipative polymeric network within the bulk layer of the film – allowing electrostatic charges on the film surface to dissipate throughout the external layer. The antistatic effect is


immediate, consistent during the lifetime of the film and lasts as long as the film is in use, it says. Thanks to the dissipa-


tive effect, powder can be emptied from packag- ing more effectively, as the anti-stat prevents some particles from remaining inside due to the static effect. In sealed bags, it can eliminate the presence of static powder in the sealing area. � www.ampacet.com
