UFLEX DEVELOPSROBUST SEAL PERFORMANCE

CPP FILM

By: Uflex Ltd

ADDRESSING DIVERSIFIED PACKAGING NEEDS

• India’s largest global flexible packaging company Uflex Ltd. has developed Cast Polypropylene (CPP) Film with Robust Seal Performance

• Film finds widespread use in addressing different types of packaging needs and exhibiting superior sealing functionalities

• Problem of poor run-ability of laminate on new generation state-of-the-art high speed seals Form-Fill-Seal (FFS) machines and persistent problems like seal opening at high speed; poor seal through contamination and poor hermetic seals led the engineers at Uflex develop the Robust Seal Performance CPP Film

• Robust Seal Performance CPP Film also addresses issues of variable weather conditions which often have an adverse effect on laminate performance

• The film increases the shelf life of the packed products from six months to about one year.

• Uflex launched the product in February 2016 after an extensive R&D of about one and half years

THE NEED GAP

Low SIT (Seal Initiation Temperature): For the Robust Seal Performance CPP Film, the SIT is 95 degrees centigrade which allows using a high speed FFS machine with excellent seal performance.

High and Broad Hot Tack Strength: Hot Tack Strength for the new film is extremely high (>500 gm/25 mm) over a broad temperature range (100 -145 degrees centigrade). This makes it possible to run the laminate on all kinds and generations of FFS machines.

Good Hermeticity: The film demonstrates good seal through contamination paving way for fool-proof hermetic seal. This further ensures absence of any leakage – a fact that is easily established by bubble test of the laminate of which this film is a part.

Good Optics: Optical properties of the laminate (like haze & gloss) remain competent irrespective of the engineering that goes into manufacturing the Robust Seal Performance CPP Film. In fact they are better than the standard CPP and PE Films.

PERFORMANCE CATALYST

THE FILM STANDS OUT FROM OTHER VARIANTS OF CPP ANDPOLYETHYLENE (PE) FILMS:

• The film’s applications are quite universal

• It is available in various variants such as plain, metallized and as white CPP

• Applications include snacks packaging, condiment packaging, and Over the Mountain (OTM) as the film offers good performance even at low atmospheric pressure

• A 2-layer laminate of this film can replace 3-layered traditional laminates to withstand nitrogen flushing

• Robust Seal Performance CPP Film offers cost effective improvements in packaging speed, consistent performance on packaging equipment, durable package integrity and aesthetics

• The film is carefully engineered to address diversified and challenging sealing needs of flexible packaging
