Traceable paper cups and bowls and preparation method thereof

Abstract

The invention discloses traceable paper cups and bowls and a preparation method thereof. The paper cups and bowls are provided with tracing identifiers, and tracing information is bound to the tracing identifiers for tracing display in later period. The preparation method of the traceable paper cups and bowls comprises a first mode, wherein before and after the paper cutting process or during the paper cutting process through a die-cutting machine, each piece of paper is printed with a tracing identifier, and the tracing identifiers and tracing information carried by the tracing identifiers are stored in an information system; a second mode, wherein traceable identifier printing equipment is additionally installed at a reel feed inlet in the bottom of molding equipment, after fan-shaped paper pieces and bottom reel paper are put into the feed inlet of the molding equipment, the tracing identifiers are printed at the bottoms of the products through the tracing identifier printing equipment, and meanwhile the tracing identifiers and the tracing information carried by the tracing identifiers are stored in the information system. According to the traceable paper cups and bowls and the preparation method thereof, application of a 'one object, one code' tracing mode in low-value single-item products of disposable paper cups and bowls is created for the first time, and food packaging safety and quality improvement can be greatly promoted.

Description

technical field [0001] The present invention relates to a paper cup and paper bowl and a preparation method thereof. Background technique [0002] At present, disposable paper cups and bowls are widely used in people's lives because of their low price and convenient use. [0003] The traditional production process of disposable paper cups and bowls is: base paper coating---slitting---printing---film cutting---forming---packing. [0004] Base paper lamination: that is, coat base paper with PE film with laminating machine. The paper coated on one side is called single-sided PE coated paper; the coated paper on both sides is called double-sided PE coated paper. [0005] Slitting: Use a slitter to cut the coated paper into rectangular sheets for making the wall of the paper cup and paper bowl and roll paper for making the bottom of the paper cup and paper bowl. [0006] Printing: Use a printing machine to print various patterns and texts on rectangular sheets of paper, such a...

Problems solved by technology

[0010] However, because the market is not standardized, there is a lack of effective management, there are a large number of inferior products, and it is difficult for ordinary people to identify them, which brings great hidden dangers to people's dietary health.

If it can be traced and managed, it will effectively promote the standardized management of the market and guide the healthy development of the market. However, because all the patterns of disposable paper cups and paper bowls are printed in the printing process, all patterns in the same batch of products They are all consistent, and it is impossible to print different unique traceability marks

If you want to implement variable two-dimensional code printing technology in the printing process, but the existing variable two-dimensional code printing speed can only reach a maximum of 120 m / min, while the paper printing speed reaches 250-300 m / min, Therefore, the existing technology cannot meet the

Secondly, according to the actual situation of most disposable tableware production at present, the printed paper will not be put into the next production process immediately, but often enters the inventory, waiting for the actual paper cup and paper bowl forming production scheduling

Therefore, the production time recorded in the traceability label printed in the printing process is only the production process time of the paper, not the real production time of the formed paper cup and paper bowl, so the expected effect of effective traceability cannot be achieved.
