Description

[0001] The present invention relates to a candy packaging film manufacturing method and composition,

The present invention relates to a film for wrapping candy such as peanut caramel, jelly, candy, and the like. More particularly, the present invention relates to a film for wrapping, And when the packaging is opened, the packed film is freely cut in the transverse and longitudinal directions to facilitate the opening of the packaged film, and a composition thereof.

Conventional candy wrapping paper used a wrapping paper made of synthetic resin. For example, PE (polyethylene) material is mainly used, but PE is reusable, but print sharpness is poor. It is known to use OPP (Oriented Polypropylene) fabric to enhance the sharpness and to increase the sharpness of printing by gravure printing on the back side of the OPP fabric. Also, it was fabricated by applying PE to the surface of OPP fabric or by attaching PP to the back of OPP fabric to reinforce the bending strength of the packaging paper.

However, when the packaging paper is manufactured by bonding the PP to the back side of the OPP fabric as described above, when the consumer purchases the candy or the like and peels the packaging paper, if there is no separate perforation line, the packaging paper is stretched by force, And there is an uncomfortable problem such that the candy bounces out.

Looking at the prior art in this field,

(Hereinafter referred to as " Prior Art 1 ") filed by the applicant of the present application, the " improvement in storage property and easy packaging method and packaging method" A step of forming a resin coating layer 12 by applying a resin to the inner edge of the cut after the candy is cut to a size that can be packed, a step of placing the candy 20 on the inner upper surface after cutting the silver- Folding the bag of silver foil on which the candy is placed in half to fold the resin coating layers 12 so that they are superimposed on each other, and folding the bag of silver foil 11 so that the candy is wrapped, To form a thermally adhering portion 13 by thermally fusing three surfaces so that the thermally adhered portion 13 and the thermally adhered portion 13 are adhered to each other; V "or" l " (14) is folded so as to be positioned on the upper surface of the packed candy, and then both ends of the folded portion are folded so as to be sealed. The wrapping paper is wrapped And the three sides of the edge of the silver foil wrapping paper are heat-pressed to form a heat-bonding portion (13) in which the resin coating layer is thermally fused, and the ends of both sides are tied and sealed.

As another prior art, the "composition and method for selectively crosslinking a film and an improved film product made therefrom" of Patent Publication No. 0486011 (hereinafter referred to as "Prior Art 2 & (a) at least one polyene monomer, (b) at least one C 2 -C 20 olefin monomer, and optionally (c) at least one polymerizable unit derived from at least one copolymerizable monomer other than (a) coalescence; or

(ii) one or more polymers having (a) polymeric units derived from one or more polyene monomers, and (b) one or more C 2 -C 20 olefin monomers and optionally one or more (PCE) composition comprising a polymer blend comprising at least one polymer having polymeric units derived from copolymerizable monomers as an inner layer of the film, wherein one of the one formed of the PCE composition A multilayer film having a higher degree of cross-linking than one or more other sealable layers wherein each of the inner layers above forms the main surface of the film is disclosed.

However, in the prior art 1, since the wrapping film tears in one direction, there is an inconvenience that the cut-out portion should be displayed in advance so that the wrapping film is cut into a predetermined standard at the time of manufacture, , The packaging can not be confirmed if the packaging is done while the packaging is in the opposite direction, so that the packaging material is not torn in the process of tearing the candy wrapper.

Also, the prior art 2 is capable of providing improved crosslinking efficiency to a multilayer film contained in one or more layers, which may be useful for the production of flexible packaging films for use in food packaging, That would be inappropriate. That is, while the pastry and candy packaging has the convenience of being smoothly peeled off when the package is torn for consumption, prior art film structures may be suitable for general food packaging, In case of using as a wrap film, there is a problem that the contents are broken when the contents are cooked in the process of tearing the package. In case of the candy, the candy is uncomfortable because it exerts excessive force in peeling the package .
