Adhesive 62Vst

Application and use

The PSA 62Vst is characterized by an extraordinary high tack. Even on critical surfaces tack-level is very high. 62Vst is therefore ideal for cool, moist and even slightly greasy surfaces. 62Vst shows excellent low temperature suitability. Once labelled 62Vst is highly waterproof.

Processing

Excellent die-cutting characteristics on all customary machines.

Storage conditions and shelf life

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 up to 2 years from date of production (belongs to face material).

Regulations concerning contact with food

The product is subject of Food-Contact Notification (FCN) 865, which has become effective March 19th, 2009, following review by the United States Food and Drug Administration (FDA). 62Vst may be used as the food-contact surface of labels applied to food, compliant with 21 C.F.R. § 175.125(a) or (b), under conditions of Use D through G, as described in Table 2 of the FDA publication "Definitions of Food Types and conditions of Use for Food Contact Substances".

The pressure-sensitive adhesive 62Vst can be safely used for the back coating of labels for labelling of foodstuffs for storage at room temperature or 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. Furthermore, the adhesive may be used for laminating various materials. In this case, cut edge contact with food is harmless as far as the above mentioned adhesive is concerned. It must be ensured that the relevant migration limits are complied with by the laminated packaging (Declaration of no objection valid until 14.12.2025).

Furthermore the self-adhesive labels with the adhesive 62Vst can be used for labelling of blood bags (Expert's Opinion from December 16, 2021).
