BOPP anti -fog film is a functional thin film that prevent water vapor from fog on the surface of the film. It is mainly used for displayed packaging of fresh products such as vegetables, fruits, flowers, flowers, sushi, cold fresh meat.
Because the packaging bag made of ordinary BOPP film is packaged in the above fresh products, due to the large water content of the fresh products itself, the temperature has changed a lot during the storage and transportation process. The opaque water mist leads to the user's unable to see the goods in the bag, and the goods in the bag are easily spoiled and corrupted after contacting the water mist, which rapidly shorten the shelf life of fresh products and the emergence of the anti -fog film. Not only improves the display of fresh products, but also effectively extends the shelf life and listing period of fresh products, so it is applied to supermarkets in large quantities.
BOPP anti -fog film has excellent anti -fog, high thermal sealing strength, high heat intensity, high smoothness, high opening, high puncture resistance, high transparency, and safe, hygienic, non -toxic and harmless. At present, according to its characteristics, further development can also be developed in terms of functionality.
Conquesting the domestic BOPP industry cannot do the difficulty of anti -fog film, and can control the display temperature and time according to the size of the anti -fog additives and the amount of person.
Key technical content: Formulating technology of anti -fog maternal material; proportion of anti -fog materials when producing BOPP; The amount of anti -fog agent is insufficient, the anti -fog aggressive fruit difference, the percentage of the plus percentage increases the fog, the obtaining difficulty is difficult, and the cost increases. At the same time, the selection and amount of the anti -adhesive agent must also find a balance between the opening and the mist. Anti -fog membrane requires high heat sealing. The ordinary thermal sealing membrane only needs to reach 10N/15mm, while the anti -fog film requirements are greater than 20n/15mm.
In order to achieve the effect of high and low temperature and fog: In the refrigerator at 0 ~ 4 ° C, it is placed for 24 hours. Above 60 ° C and 0 ° C: The repeated alternation environment is 24h, and there is no fog on the surface of the film.
The above is an introduction to the purpose and performance of "packaging film manufacturer: BOPP anti -fog film!" Shenzhen Xianzi Biotechnology Co., Ltd. is a professional development and production of BOPP film, POF contraction membrane, Yila wire and other products Manufacturers have long provided users with BOPP film and POF shrinking film wholesale and customization services for a long time.
