Abstract
Provided is a fruit and vegetable fresh keeping packaging bag or box. The packaging bag or box is made by using an ultrafine fiber cloth as a base material, wherein a fluff layer is arranged on one side of the ultrafine fiber cloth, a food grade plastic thin film layer is formed on the other side of the ultrafine fiber cloth in a compression molding mode, the plastic thin film layer is the outer layer of the packaging bag or box, and the fluff layer is the inner layer of the packaging bag or box. The fruit and vegetable fresh keeping packaging bag or box not only has the original function of a common plastic fresh keeping bag, but also has strong functions of water absorption, moisture preservation and carbon dioxide absorption. When the fruit and vegetable fresh keeping packaging bag or box is used for keeping fruits and vegetables fresh in cold storage, the problem that liquid water is generated in the fresh keeping process can be solved, the fresh keeping effect of the fruits and vegetables can be improved remarkably, and the fresh keeping period of the fruits and vegetables can be prolonged greatly.
Description
Technical field
The present invention relates to a kind of Fresh-keeping Packaging for Fruits and Vegetables bag or case, belong to postharvest technology of fruits and vegetables field.
Background technology
When doing the experiment of the preserving fruit and vegetable utilizing such as lichee, spinach, finding in preservation process, there is many liquid waters in the bag wall of freshness protection package, and these water are easy to adhesional wetting pericarp, dish leaf and cause fruits and vegetables variable color to be rotted, and greatly shorten the cold storing and fresh-keeping phase of fruits and vegetables.
Summary of the invention
The object of this invention is to provide and a kind ofly can significantly improve the fresh-keeping effect of fruits and vegetables, the Fresh-keeping Packaging for Fruits and Vegetables bag greatly extending the freshness date of fruits and vegetables or case.
A kind of Fresh-keeping Packaging for Fruits and Vegetables bag provided by the invention or case, this packaging bag or case have tapetum with one side, another side compression moulding has the superfine fibre cloth of food grade plastic thin layer to be that base-material manufacture forms, wherein, plastic film layers is the skin of packaging bag or case, and tapetum is the internal layer of packaging bag or case.
Plastic sheeting layer thickness is 0.01 ~ 0.5mm, and preferably plastic sheeting layer thickness is 0.1 ~ 0.3mm.
Its method for making is:
First make the superfine fibre cloth of single-side pile batt, then at downless one side compression moulding layer food level plastic film layers, mould
Material thin film layer thickness can thick can be thin, be generally 0.01 ~ 0.5mm, specification as required and shape are processed into Fruit and vegetable preserving bag or packing chest, and wherein, plastic film layers is the skin of packaging bag or case, and tapetum is the internal layer of packaging bag or case.
This freshness protection package or case not only have the original function of common plastics freshness protection package, meanwhile, also have the function of strong water suction moisturizing and absorbing carbon dioxide.With this packaging bag or case, cold storing and fresh-keeping is carried out to fruits and vegetables, not only can solve very well in preservation process and occur liquid water problem, and the fresh-keeping effect of fruits and vegetables can be significantly improved, greatly extend the freshness date of fruits and vegetables.
Detailed description of the invention
