Abstract

The plastic film tape that a kind of packaging product is used (1) comprises a pair of adjacent wall (3,4), is formed by the longitudinal folding of heat seal property plastic film belt, and line is laterally sealed on the edge, and (6,6a 6b) interconnects, described envelope line (6,6a 6b) extends to the opposite side (3a of described wall (3,4) from longitudinal folding limit (5), near side (ns) place 4a), and described opposite side (3a, near side (ns) place 4a) have at least one hole (8,8a).

Description

The present invention relates to different product, particularly the packaging bag that is obtained by transverse sealing is produced used type products web-like thermoplastic film wrapping and that can separate use separately and is with.

The crowd is used to be known, existing product is packed into worked around belt to reel according to certificate by the machine of the heat-sealing mouthful packaging bag that the plastic sheet material is made, by continuous operation position, form the packaging bag that can hold product, product is loaded in the packaging bag on next loading station.

So, must arrange belt suitably, so that it sends into the charging machine.

In addition, the inside, bottom of above-mentioned packaging bag has the corrugated folding usually, feeds with being convenient to the increase capacity, and therefore, at this folding place, its square section thickness obviously increases.

In this case, the seasoning of flaky material, the particularly coiling of film band on reel so that make a kind of product be used for the machine of common thermoplastic plastic packaging bag that product is packed into easily, have just become difficulty.In fact, such reel is wayward during very unstable and packing when forming, and this is to cause owing to respective diameters difference that the above-mentioned cross section thickness difference of film band causes.

The thermoplastic film who the objective of the invention is to be suitable for sending into by design loading machine is with, so that the different product packing solves the problems referred to above.

Another purpose in purpose scope of the present invention provides the thermoplastic film who is suitable for reeling and is with on reel, so that form the packaging bag of different product.

According to the present invention, above-mentioned two purposes are that the film by packaging product brings and finishes, it is characterized in that it has comprised at least two adjacent walls, it is that vertical folding by the heat sealability plastic sheeting forms, and connect together along laterally sealing line, described horizontal envelope line is the vicinity that reaches the relative edge of described wall from vertical folding edge, and, in the vicinity of described opposite side, has a hole at least.

Details of the present invention will can obviously be found out from the detailed description of some most preferred embodiments of the web-like thermoplastic plastics belt of described packing different product in conjunction with the accompanying drawings.Wherein,

Fig. 1 is the transparent view of strap part of the present invention;

Fig. 2 is the transparent view for the film band of the vertical folding that is rolled into reel;

Fig. 3 is the reel scheme drawing that described film band forms;

Fig. 4, Fig. 5 and Fig. 6 are the scheme drawing of explanation according to other form of the present invention.

Referring to described accompanying drawing, reference number 1 general proxy heat-sealing plastic material to be rolled into the film band of reel 2.Film band 1 comprise two by the vertical folding of plastic sheeting and longitudinally flanging form inner corrugated folding 5 and the

wall

3,4 that obtains.

Wall

3,4 is along envelope lines 6, for the longitudinal length of film band and equidistant and laterally connect together.Envelope line 6 defines a series of adjacent bags 7, to be adapted to constitute the bag of individual packages separately of packaging product.

Laterally envelope line 6 extends to its relative edge's vicinity by described vertical flanging, and wherein corrugated folding 5 forms bag ends, does not influence the edge 3a of

wall

3,4 like this, 4a.These limits 3a, 4a determines its opening, can put into by the product that this opening is packaged.

Best, described horizontal envelope line is by a pair of adjacent envelope line 6a, and 6b constitutes.Between this is to line, line of cut can be arranged, can realize cutting apart of each independent bag like this.

Approach limit 3a, an end of the envelope line 6 of 4a is provided with hole 8, and this hole obtains by hole punched device, and generally is located at line 6a, and is between 6b, relatively good like this.Hole 8 is that attempt allows feeding conveyor by charger commonly used to make to be with 1 transmission.Can provide overlapping hole 8 equally, 8a, another then guarantees to carry out the separation of packaging bag at the upper area of film band owing to the hole that provides in advance along the envelope line under the situation that line of cut does not have to aim at even one of them is as locking.

But for making the film band be convenient to the coiled reel, the vertical folding of

wall

3,4 self, so that tabs 3a, 4a 5a place in the zone of corrugated folding 5 is continuous.The folding part of film is represented with label 9 in the drawings, regional in one's power the thickness of film band is doubled.The film band has identical thickness on its cross-sectional plane like this, because be not subjected to the thickness at corrugated folding 5 places of the influence of folding part 9, has been repetition.

So final permission forms the reel 2 of fixed diameter, from the viewpoint of its production and use obvious advantage is arranged all.

Easily, folding part 9 is carried out folding at the film band with respect to the outside of reel 2 spools, and this is more favourable.Hole 8 is towards the outside like this.

Make band be rolled into the structure that reel has been simplified charger greatly in advance, because band can separately produce with equipment, its running velocity is disobeyed and is disinclined to the running velocity of charger.Can be used for several charger simultaneously with such equipment, basic progress of the present invention is to make band and conveyer to combine and offers charger, particularly, conveyer has the hook component that can enter hole 8, is transferred to charger so that band is combined on the conveyer and it.

Now according to another aspect of the present invention, laterally seal the end place of line 6, approach edge 3a, there is a zone 10 that enlarges at the 4a place, and has hole 8 on it, as shown in Figure 4.

As shown in Figure 5, enlarged 10 is envelope line 6a, and the end place of 6b links together, and can form a pair of perforate 8,8a thereon.

In addition, can also form pre-tangent line or line of weakness 11, as shown in Figure 5 and Figure 6, be separated the preferable line of packaging bag with qualification.

In an embodiment of the present invention, used material, and shape and size can be various ways as required.
