Description

Technical Field

[0001] The present invention relates to the technical field of paper bag equipment and technology, and in particular to a manufacturing device and a manufacturing method of a takeaway handbag with a double-sided release paper handle patch capable of achieving bag opening adhesion. Background Art

[0002] Handle bags are also called handbags, handbags, etc., which are used to hold items. The materials used to make them include paper, plastic, non-woven fabrics, etc. The commonly used paper packaging bag handles on the market mainly include rope-threaded and paper-made ones, and most of the paper handles are open. In current technology, handbags used for takeout purposes are generally required to have certain insulation functions and handle functions; in most cases, the paper rope is pasted on the inner surface of the handbag, which realizes the hand-carrying function without destroying the appearance of the paper bag; the conventional paper rope pasting is realized and formed by sandwiching the hand-carrying paper rope in the middle with two ordinary patches on both sides, and the patch facing the inside of the bag opening has no sealing function. The patch is only used as an adhesive sheet for the hand-carrying paper rope to be pasted on the inside of the bag opening, that is, the two facing patches have stickiness on one side and no adhesive effect on the other side, which cannot realize the purpose of sealing the bag opening after the corresponding food is loaded, so as to keep the food or beverages and other loads warm for a long time, and cannot prevent the loads from accidentally falling out of the handbag. In addition, during the delivery process of takeout, the handbag with the bag opening opened is also susceptible to environmental influences such as weather, humidity, and temperature, which may cause the load to be contaminated or the quality to be degraded. Therefore, in order to avoid the shortcomings existing in the prior art, it is necessary to make certain improvements to the prior art to develop a takeout handbag that can seal the bag opening after the load is placed in the bag. However, the existing production equipment all adopts machines adapted to the production of single-sided stickers, hand-pulled paper ropes, and bags. There is no special equipment for the production device and process with bag opening sealing function, and it is not suitable for the preparation of takeout handbags with bag opening sealing, especially for the production equipment for double-sided stickers formed by double-sided adhesive and release paper at the bag opening and applied to takeout handbags. Therefore, the production device and process of takeout handbags need further research and development and improvement to be suitable for the production of takeout handbags with release paper and double-sided adhesive to achieve bag opening sealing function. Summary of the invention

The takeaway handbag has strong viscosity and is not easy to separate. It is not easily affected by weather, temperature, humidity and other factors. The bag is more firm and practical. The takeaway handbag production device has the function of online production, automatically pasting the handle on the paper bag to form and produce a complete takeaway handbag product together. The paper bag can be produced first and then the handle can be pasted for offline production. The bag can also be folded manually and the handle can be pasted to complete manual production.
