Thermoprinting carbon foil

Abstract

The present invention discloses a kind of thermoprinting carbon foil used for soft plastic package and the thermoprinting carbon foil consists of belt base and painted thermal transfer carbon layer. The present invention features the thermal transfer carbon layer comprising resin 32-41 wt%, plasticizer 5-11 wt%, polyethylene wax 2.2-7.7 wt%, dispersant 0.1-0.5 wt%, and pigment 16-39.8 wt%. The thermoprinting carbon foil may be transfer printed in large area with thermal transfer equipment, and the maximum transfer printing area is 150x150 mm. The thermoprinting is boiling resistant and fadeless. The present invention makes it possible to obtain clear scrape resisting and boiling resisting text and pattern outside the package of PE, PP, PET, PVDC and other non-PVC material.

Description

technical field [0001] The invention belongs to a kind of foil, in particular to a hot-printing carbon foil used in the occasion of printing on the outside of a plastic flexible package. Background technique [0002] According to the novelty search report of the Henan Provincial Institute of Science and Technology Information, there are several similar invention patents in China, all of which have technical defects in terms of their reported performance. The Chinese patent with the notification number CN1052450A discloses a Heat-sensitive ribbon for surface transfer printing, the application of this heat-sensitive ribbon has poor scratch resistance, is not resistant to cooking, and cannot meet the hygienic conditions for the production of infusion bags; according to the technical characteristics described in the 92200909 (Cheng) The carbon layer can only be transferred in a small area, that is, it can be transferred on the scale of one or two lines of characters, and cannot ...
