寧波牛皮紙箱可以用來存放物品或包裝一些易損產(chǎn)品，但是一些穿透能力很強(qiáng)的糧食害蟲，可以穿透包裝紙板，不僅損害其中的食品，也損害了食品生產(chǎn)廠家和銷售商的聲譽(yù)，因此西安中天包裝有限責(zé)任公司想出了兩種防蟲方法。
Ningbo Kraft cartons can be used to store goods or pack some vulnerable products, but some insect pests with strong penetration ability can penetrate the packaged cardboard, which not only damages the food, but also damages the reputation of food manufacturers and sellers. Therefore, Xi'an Zhongtian Packaging Co., Ltd. has come up with two ways to prevent insects.

1.物理方法，即用強(qiáng)度較高的薄膜包裝單個食品，使蟲子穿不透而防蟲。但這種方法必須改變現(xiàn)有的包裝生產(chǎn)線，另外也格外增加了薄膜的成本。

Physical method is to pack individual food with high strength film, so that insects can not penetrate and prevent insects. But this method must change the existing packaging production line, in addition to increasing the cost of film.

2.采用化學(xué)的方法，即用涂有化學(xué)藥劑的紙板包裝食品以防蟲，其具體做法是在紙板的表面，涂上防蟲漆。這種防蟲漆不是殺蟲劑，而是可以作為食品添加劑的天然精油，其作用不是殺蟲，而是驅(qū)蟲，從外部防止蟲子的侵入。這樣可以不改變現(xiàn)有的包裝生產(chǎn)線，保持較低的成本。其加簡單，可以用苯胺印刷機(jī)印到紙板表面上，適于小批量生產(chǎn)，廢紙板可以回收再生。

The chemical method is to pack food with cardboard coated with chemicals to prevent insects. The specific method is to coat the surface of cardboard with anti-insect paint. This insect-proof paint is not an insecticide, but a natural essential oil that can be used as a food additive. Its function is not to kill insects, but to repel insects from the outside to prevent the invasion of insects. This will not change the existing packaging production line, maintain a lower cost. It is simple and can be printed on the surface of cardboard by aniline printer. It is suitable for small batch production. Waste cardboard can be recycled.
