Description

File protection bag and folder

Technical Field

The present application relates to flexible packaging bag technology, and in particular, to a file protection bag and a file folder.

Background

At present, a file protection bag is commonly used for placing and protecting files or cards, the existing file protection bag at least comprises two layers of protection films, the two layers of protection films form an upper opening or a side opening, protected objects such as business cards, photos, files and the like can be inserted into the file protection bag in a straight insertion mode or a side insertion mode, and the two layers of protection films are respectively attached to the front side and the back side of the protected objects to play a role in protection.

However, the conventional document protection pouch has the following drawbacks:

(1) The protection Film of some file protection bags adopts single material, if some file protection bags use OPP Film (Oriented Polypropylene Film), can make the internal surface of file protection bag take place adhesion, glutinous mouthful, and resistance is great when inserting the protection object, even the unable opening of inserting of protection object.

(2) The common file protection bag in the market at present is a PP Film (Polypropylene Film) formed by a Film blowing process, and has the defects of low transparency and difficulty in meeting the requirement of laser pattern effect.

(3) In order to avoid the adhesion of the inner surface of the document protection bag and enable the document protection bag to have better stiffness, the protective film structure of part of the document protection bag is more complex, for example, part of manufacturers compress a layer of multilayer composite film with better comprehensive performance by using various materials such as OPP film, kraft paper, other PP films and the like, and the multilayer composite film is used for processing the document protection bag, and the document protection bag has the problems of complex processing technology and higher production cost.

SUMMERY OF THE UTILITY MODEL

In order to overcome the disadvantages of the prior art, an object of the present application is to provide a document protection pouch, which has a simple protective film structure, and in which the inner surface of the document protection pouch is not easily adhered and stuck, and is easily inserted into a protection object.

It is a second object of the present application to provide a file folder that includes a file protection pocket.

In order to achieve one of the purposes of the application, the technical scheme adopted by the application is as follows:

file protection bag, including OPP membrane and CPP membrane, the OPP membrane is equipped with first connecting portion, the CPP membrane be equipped with the second connecting portion that first connecting portion correspond, first connecting portion with the second connecting portion are connected in order to form the holding chamber that is used for placing the protection object, and are used for supplying the protection object gets into the uncovered in holding chamber.

Preferably, the first connecting portion and the second connecting portion are formed by hot press molding or ultrasonic molding.

Furthermore, the accommodating cavity is substantially square, the first connecting portion and the second connecting portion are connected to form a first pressing edge, a second pressing edge and a third pressing edge, two ends of the first pressing edge are respectively connected with the opening and the second pressing edge, the second pressing edge is located at the bottom of the accommodating cavity, and the third pressing edge and the first pressing edge are symmetrically arranged about the second pressing edge.

Furthermore, at least one of the first stitching edge, the second stitching edge and the third stitching edge is provided with a binding part, and the binding part is used for binding the file protection bag.

Further, the OPP film is provided with a first open side, the CPP film is provided with a second open side, the first open side and the second open side surround to form the opening, and the length of the first open side is larger than or equal to that of the second open side.

Preferably, the OPP film and/or the CPP film is a laser film.

Preferably, the document protection pouch comprises at least one layer of OPP film and one layer of CPP film.

Preferably, the OPP film has a basic thickness of 0.03mm to 0.1mm, the CPP film has a basic thickness of 0.03mm to 0.1mm, and the OPP film has a basic thickness which is the same as or different from the basic thickness of the CPP film.

In order to achieve the second purpose of the present application, the technical solution adopted by the present application is:

a file folder comprising the file protection pouch.

Compared with the prior art, the beneficial effect of this application lies in:

the holding chamber both sides of file protection bag are the OPP membrane respectively, the CPP membrane, at first the OPP membrane has better deflection, and the transparency is higher, make the inside visual of file protection bag, secondly the CPP membrane is softer, be difficult for with the adhesion of OPP membrane, can prevent to take place glutinous mouthful, reduce the resistance when inserting the protection object, the OPP membrane makes the non-adhesion of file protection bag with CPP membrane combined action, glutinous mouthful not, easily insert paper, effectively compensate the too soft problem of CPP membrane, furthermore, compare the file protection bag that multilayer complex film was processed, the file protection bag of this application still has the structure fairly simply, advantage that the processing cost is low.
