"Food" is at ease, the marking application of 355nm UV laser in the packaging of prefabricated vegetables

Chinese cuisine is rich and varied, and a variety of flavors are very popular. Braised chicken rice, tomato brisket, Kung Pao chicken, garlic crayfish, Hu spicy soup... There are many special dishes from all over the world. However, in the current fast-paced life, it is time-consuming and laborious to complete these dishes in your own kitchen, from preparation to final product, which is not a small challenge.

In addition, affected by the current epidemic, many restaurants do not allow dine-in, and takeaways have many hidden dangers in food safety and hygiene, so pre-made dishes have become popular and become a "sweet pastry" in the eyes of busy office workers, and quickly ushered in rapid growth. Tear off the outer packaging, and the fish-flavored shredded pork, Dongpo pork, sweet and sour pork ribs with all the colors and aromas can be quickly presented on the table after a few minutes of heating.

What is a prepared dish? It may sound mysterious, but it's actually not that complicated. It is a finished product or semi-finished product processed from agricultural, livestock, poultry and aquatic products, and is hygienically and scientifically packaged and preserved by a series of methods such as freezing or vacuuming. As a convenient special dish on the table, it has the characteristics of convenience, efficiency and stable production.

According to the survey, nearly 30% (29.03%) of consumers expressed their greatest concern about the food safety of prepared dishes. Therefore, in addition to strengthening the control and transportation and preservation of ingredients, the packaging of prepared dishes is also particularly important. There are two main packaging methods for pre-made vegetables, vacuum bag packaging and air-conditioning lock fresh box packaging. They generally use PET/BOPP as the printing film. If the pre-made vegetables are positioned high, three-layer composites can also be used, that is, the outer layer is made of PET. /BOPP, use PETAL in the middle, and then compound a layer of CPP or PE as a heat sealing layer, which plays the role of moisture barrier and gas barrier and prevents deterioration.

사전 제작된 야채 포장을 밀봉한 후 제품 추적성과 효과를 발휘하기 위해 외부 포장에 제품의 브랜드, 생산 날짜, 유통 기한, 사양 번호 및 기타 정보를 명확하게 표시해야 하는 경우가 종종 있습니다. 위조 방지 및 위조 제품의 출현을 방지합니다. 현재 주류 마킹 방법에는 잉크젯 코딩과 레이저 마킹이 포함됩니다. 잉크젯 코딩 기술은 성숙했지만 환경 오염 문제가 있고 잉크를 자주 추가해야 하며 정보가 쉽게 떨어지고 쉽게 변조될 수 있습니다.

레이저 마킹 방식이 다릅니다. 잉크젯 코딩 방식에 비해 환경 친화적입니다. 그것은 영구적인 마크이며 쉽게 변경되지 않으며 떨어지지 않습니다. 그것은 많은 식품 회사의 생산 라인에서 사용되었습니다. RFH 355nm UV 나노초 레이저를 준비된 접시의 생산 라인에 통합하면 7*24시간의 장기 마킹을 달성할 수 있으며 빔 품질이 높고(M2 < 1.2) 초점을 맞춘 후 플레이트의 직경이 작고 마킹의 인식 정도는 매우 높으며, 355nm 자외선 파장 + 약 20ns의 펄스 폭, 외부 포장 필름에 대한 이러한 조합, 높은 단일 광자 에너지는 냉간 가공 효과, 좁은 펄스 광대역을 매우 작은 열 영향 영역에 가져옵니다. 날짜 표시부터 원산지 정보, 패턴 데코레이션까지
