Embodiment Construction

[0006] Embodiments are further described in conjunction with the above figures. The present invention is an improvement carried out on the basis of the prior art. It is to print a varnish layer 3 respectively within the range of 2-3 centimeters from each color mark 4 on the upper surface of each printed graphic layer 2 of the heat-shrinkable film base layer 1. . Through the above improvements, each block of printed graphics is thermally covered with a varnish layer, which can effectively prevent the graphics from being polluted without affecting the thermal division of the heat-sealing knife, and has the advantages of simple structure, low cost and high efficiency.

Abstract

The invention discloses a food packaging heat shrinking film printed with pictures and texts, which comprises a heat shrinking film basic layer, wherein picture and text layers and sealing and cutting color batches are sequentially printed on the upper surface of the heat shrinking film basic layer at intervals, and a gloss oil layer is respectively printed on the upper surface of each printed picture and text layer within a range of not smaller than 2-3 centimeters away from both sides of each color batch. A gloss oil layer is respectively covered on the surfaces of the printed pictures and texts by keeping away from the color batches, so the phenomenon that the gloss oil adheres to a knife when in cutting can be effectively avoided; and the food packaging heat shrinking film has the advantages of good picture and text protection effect, high production efficiency and low cost.

Description

Technical field: [0001] The invention relates to a layered product, especially a heat shrinkable film for food packaging that can prevent ink printed on the heat shrinkable film from falling off. Background technique: [0002] In the existing heat-shrinkable film for POF food packaging, the ink printed on the outer surface of the film layer is easily contaminated by oil and falls off, making the printed image blurred. Therefore, the product with a lot of oil content Usually, composite packaging rolls are used to print the graphics and texts inside, or the graphics and texts are pre-printed on the paper card, and the card is built into the heat shrinkable film to avoid the blurring of the graphics and texts. The above method not only increases the packaging cost, but also affects the production efficiency. Invention content: [0003] The object of the present invention is to provide a heat shrinkable film for food packaging printed with pictures and texts, which has low pa...
