TECHNOLOGY | MATERIALS POLYOLEFIN FOAM PP foam used in high temperature tape


Sekisui Alveo has developed a thin polypropylene (PP) foam for high-tem- perature adhesive tape applications. Alveolit TP SE combines flexibility


with strength and maintains stability at elevated temperatures where standard polyethylene foams fail. It is a blend of various polymers: a skeleton of PP gives temperature resistance and strength; a matrix of a rubber-like polymer provides softness; and a speciality polymer enables the two polymers – which are not typically compatible – to stay together and form a fine-cell foam.


BOPP FILM


BOPP film for fresh


produce Innovia Films has launched P2G, a BOPP film for flow wrap applica- tions in fresh produce packaging.


By optimising gas


transmission rates, the film supports respiration control, enhancing freshness and extending shelf life, says Innovia. P2G is heat-sealable on both sides, ensuring secure, consistent sealing. Its high optical clarity maintains clear visibility. It also retains its puncture and impact resistance at low temperatures, offering protection during trans- portation and storage. “P2G represents the


next generation of fresh produce packaging,” according to Megan Hinkley, senior product manager for packaging at Innovia Films. � www.innoviafilms.com

The foam has proved to be stable in double-sided tape applications at temperatures up to 150°C. Here, standard PE foam is not stable and loses its cellular structure. To date, only polyurethane foams could provide a good bond at these harsh conditions, it says. “This sets a new benchmark for thin,


heat-resistant tape carriers,” said Lukas Berger, application development manager at Sekisui Alveo. “It performs where other foams lose their cellular structure.”


RECYCLATE


Nova delivers first batch of rPE for use in stretch film products


Nova Chemicals has shipped its first batch of Syndigo rPE-IN3 recycled polyethylene (rPE) to Sigma Plastics Group in the US.


Sigma will use the resin – amounting to around 200,000lbs (90 tonnes) – to make stretch film. The material will be incorpo- rated into products such as Sigma’s Sustain360 PCR stretch film line – which includes hand films for manual application and machine films used for palletized load contain- ment. Sustain360 films integrate post-consumer recycled (PCR) content while maintaining mechan- ical properties. They are available in multiple gauges to meet the needs of modern stretch wrap- ping applications. “This first railcar shipment reflects both

companies’ shared commit- ment to advancing circular solutions in flexible packag- ing,” said Mark Lauzon, strategic account executive at Nova Chemicals. The new line of recycled LL/LDPE grades is suitable for applications including can liners, protective packaging, carry out bags, overwrap, shrink film and heavy duty sacks. The rPE-IN3 grade is made from


The facility was commis- sioned in 2025 and is expected to reach full annual production capacity of over 100 million lbs annually this year. Alan Schrob, director of mechanical recycling at Nova, said: “Syndigo1 shows that film-to-film recycling is very real. We are excited to make them widely available in commer- cial quantities.” � www.novachem.com

ard automotive interior trim applica- tions by several car manufacturers. The new foam – which has already been used in standard automotive interior trim applications by several car manufacturers – is less dense than PUR-based foam for equivalent high- temperature performance. It is available in thicknesses of 1.0-4.0mm. Other thicknesses can be developed to meet application requirements, says the company. � www.sekisuialveo.com
