CN2340710Y - Laser holographic safety line composite flexible packaging bag - Google Patents

Abstract

A laser holographic safety line composite soft packaging bag belongs to the technical field of packaging. The laser holographic safety line is formed by cutting a plastic film after laser holographic die pressing and is provided with laser holographic images or marks and characters. Because of the preparation degree of difficulty of safety line itself is great, and technical content is higher, has better anti-fake performance, the utility model discloses wide in application especially more has ideal antifalsification and authentication effect under the inner film opaque state.

Description

Laser hologram catch siding composite soft packaging bag

The utility model relates to a kind of soft packaging bag that sandwiches the laser hologram catch siding in the composite soft packaging bag, belongs to the structure design of composite soft packaging bag.

Existing composite soft packaging bag is two-layer or two-layer above plastic sheeting and makes, generally carry out colored printing in the inboard of outer membrane, literal and pattern with contents such as the title that shows and show bag interior thing, maker, trade marks, because colored printing commonly used is a current techique, technology content is lower, and its character pattern is easily by imitated personation.

It is higher that the purpose of this utility model provides a kind of technology content, the novel combined package bag that anti-counterfeiting performance is good.

The utility model is a laser hologram catch siding composite soft packaging bag, mainly is composited by outer membrane and internal layer membrane, it is characterized in that accompanying between described outer membrane and internal layer membrane the laser hologram catch siding.This laser hologram catch siding is for cutting the plastic sheeting that forms behind laser holographic molding.

Accompanying drawing has provided structural representation of the present utility model;

Fig. 1 is a Facad structure scheme drawing of the present utility model;

Fig. 2 is an A-A face cutaway view shown in Figure 1;

Fig. 3 becomes Facad structure scheme drawing behind the bag for the utility model;

Fig. 4 is a B-B face cutaway view shown in Figure 3.

Below in conjunction with embodiment the utility model is further described:

Laser hologram catch siding described in the utility model 1 adopts aluminizes or not aluminum-clad plastic sheeting is cut to batch behind laser holographic molding and made; Described outer membrane 2 is made for transparent plastic material, and its inboard is printed on the literal and the pattern of contents such as the title that can show bag interior thing, maker, trade mark, composition; Internal layer membrane 3 can be made for transparent plastic material, also can select opaque material according to the requirements such as lucifuge of thing in the bag, as aluminium foil or metallized film etc.During manufacturing, at first rolling after the colored printing is carried out in outer membrane 2 inboards by orthodox method; Simultaneously plastic sheeting is carried out cutting to batch behind the laser holographic molding making laser hologram catch siding 1, then outer membrane 2, laser hologram catch siding 1, internal layer membrane 3 are placed respectively on the unwinding rack of compounding machine, and laser hologram catch siding 1 sandwiched between the inside and outside layer film, on compounding machine, the inside and outside layer film that accompanies the laser hologram catch siding is carried out compound laminated film as illustrated in figs. 1 and 2.This laminated film is placed on the unwinding rack of Bag Making Machine and carry out bag by traditional bag-making method, make it three peripheries and form heat seals place 4, can seal a remaining periphery during use after in the bags of packing into such as food, the article in the bag are wrapped up by internal layer membrane.The position of described laser hologram catch siding 1 in soft packaging bag can be edge heat seal place or middle any position.As be clipped in the edge, can make it more to become attractive in appearance with wherein on one side heat seal place is overlapping.

The utility model reasonable in design, itself manufacture difficulty of laser hologram catch siding is higher, and technology content is higher, and packaging bag is used merchant's literal or pattern, sign to print on it, has antiforge function preferably; Simultaneously it is just sandwiched between the inside and outside layer film in packaging bag composite membrane-forming operation, make this be attached to above-mentioned antiforge function on the soft packaging bag securely effectively, not influenced by the whether transparent of internal layer membrane, make the customer when buying, can easily recognize the true and false by the test safety line.The utility model Applicable scope is wider, especially under the opaque state of internal layer membrane, has more desirable anti-counterfeiting performance and identification result.

Claims (2)

1, a kind of laser hologram catch siding composite soft packaging bag is composited by outer membrane (2) and internal layer membrane (3), is characterised in that altogether to accompany laser hologram catch siding (1) between described outer membrane and the internal layer membrane.

2, by the described laser hologram catch siding of claim 1 composite soft packaging bag, its feature is to cut the plastic sheeting that forms behind laser holographic molding in described laser hologram catch siding.
