Application and use

HERMA PP Paperprint combines the high print quality of coated paper with the durability of PP films. With HERMA PP Paperprint an excellent print quality can be achieved in all traditional printing methods such as flexo, letterpress, gravure and offset printing. Furthermore the film is perfectly suited for subsequent inscription with matrix or thermal transfer printers using resin or resin/wax ribbons. Before printing it is recommended to freshen up the corona pretreatment.

HERMA PP Paperprint features high weather and UV-resistance and is thus perfectly suited for outdoor applications.

It is recommended to convert HERMA PP Paperprint within one year from date of production.

Adhesive 42X is used where good release of the label at high initial adhesion is required. The low final tack of the adhesive provides good release on a variety of surfaces. The combination of resistance to various media, low final tack and high cohesion predestines the 42X pressure sensitive adhesive for resealable labels. Multiple opening and reclosing works very well on all common plastic surfaces.

42X shows good resistance to water, oils and other liquids. Furthermore, the adhesive has a particularly good resistance to light, moisture and ageing.

The supercalendered glassine is perfectly suited for assignment in labelling machines equipped with optical or mechanical scanners.

Processing

Excellent die-cutting characteristics on all customary machines. As part of a self-adhesive compound HERMA PW (517) offers excellent die-cutting characteristics with all customary flatbed and rotary die-cutting tools.

Storage conditions

Storing at a temperature of 20 ± 5 °C, a relative humidity of 45 ± 5 % and a dark storage is recommended. Moisture, heat and direct sunlight have to be avoided.

The shelf life is two years from date of production.

Regulations concerning contact with food

Regarding its migration behaviour, HERMA PP Paperprint comply with the requirements of directive 22/72/EC relating to plastic materials and articles intended to come into contact with foodstuffs (this directive is meanwhile replaced by regulation (EU) No. 1/211) and with regulation (EC) No. 1935/24 on materials and articles intended to come into contact with food, as well as with national regulations for food contact materials and articles. HERMA PP Paperprint can be used in direct contact for more than 24 hours up to 4 °C degrees with aqueous, alcoholic, fatty and dry food. This grade is not suitable for contact with acidic food (pH < 4,5).

The pressure-sensitive adhesive 42X can be safely used for the back coating of labels for the labelling of foodstuffs for storage at room temperature and below. It may be used in direct contact with dry, moist and fatty foodstuffs that can be assigned a correction factor of at least 2 in accordance with Regulation (EU) No. 10/2011.
