Background

At present, some liquid-packaged foods in the market contain sensitive components such as oxygen, for example, the conventional common packaged yoghurt products generally need to be stored at low temperature in the most 3 ℃ environment because the flora in the foods is sensitive to oxygen, but the common shelf life is only 21 days, and in order to prolong the shelf life, the contact between the contents and the oxygen needs to be reduced so as to inhibit the propagation speed of the flora. All the packaging cups with high barrier property are produced as soon as possible. The conventional high-barrier cup is usually a multi-layer co-extrusion structure, namely, an EVOH barrier layer is added in a cup body material during cup or sheet material injection, and the oxygen permeation amount after the material is used is greatly reduced to be less than cm3/d 24h from tens of cm3/d 24 h. By improving the barrier property of the cup body, the shelf life of the contents is greatly prolonged, and meanwhile, the storage condition is not required to be harsh in the past. Such as: at present, certain brand of normal-temperature yoghourt packaged in a cup is sold in the market, the quality guarantee period can be stored at normal temperature after the barrier cup is used, and the quality guarantee period is prolonged to 120 days.

However, when the EVOH co-extrusion cup is produced, the requirements on injection molding equipment are higher, at least three layers of co-extrusion equipment are generally needed, and the common single-layer injection molding machine cannot be realized basically.

Because EOVH is used as a barrier material, certain requirements are also made on the thickness of EVOH, the unit price of EVOH is generally higher, and the earning cost of the cup body after the material is used is also higher.

In addition, products with higher contrast appearance and performance need to be labeled, the labeling process is needed when the labeled products are packaged, so that certain influence is brought to production efficiency, and the risks of falling and ink migration are stored in the adhesive sticker, so that all products with higher relative requirements are usually processed in an in-mold labeling mode.
