Description

  The present invention relates to a paper food packaging bag made of oil-resistant paper suitable for packaging fried foods such as French fries, fried chicken, hamburgers, croquettes and the like.

  As is known, the paper food packaging bag used when taking out the fried food is made of oil-resistant paper to prevent oil from seeping out to the outer surface of the bag.

  As the oil-resistant paper, paper in which a fluorine-based oil-resistant agent is incorporated, or paper having an oil-resistant layer formed by coating the outer surface with the same oil-resistant agent is generally used.

  However, the paper food packaging bag made of the above oil-resistant paper is effective in preventing the oil from seeping out, but the oil and moisture of the fried food whose permeation has been prevented by the oil-resistant paper has accumulated on the bottom of the bag. There is a problem of causing dew condensation and impairing the texture of the fried food contained in the container, or a problem of polluting the trash box and the garbage collection site by the oil and moisture accumulated on the bag bottom.

  The present invention provides a paper food packaging bag that can effectively solve the above problems.

  In short, as a means for solving the above-mentioned problems of the paper food packaging bag made of the above oil-resistant paper, the present invention uses the oil-resistant paper as the base material of the paper food packaging bag, while the oil-resistant paper inner surface, that is, the fried food Oil-absorbing water-absorbing paper is added to the inner surface of the packaging bag that comes into contact with it. Thus, it is possible to achieve the effect of effectively preventing the oozing to the outside while properly solving the problems of bottom accumulation of oil and water and condensation.

  As the oil-absorbing water-absorbing paper, crepe-treated crepe paper is used, and by adding the crepe paper to the inner surface of the packaging bag (the inner surface of the oil-resistant paper), the oil absorption effect and the capturing effect can be enhanced.

  Preferably, the crepe of the crepe paper is oriented so that peaks and valleys of the crepe extend in the lateral width direction of the bag. This improves the effect of absorbing and absorbing oil and moisture from the fried food while trapping them in the crepe peaks and valleys.

  The crepe paper is bonded to the oil resistant paper with the top surface of the crepe crest, and an air layer is formed by a crepe valley at the bonding interface between the oil resistant paper and the crepe paper.

  While forming the paper food packaging bag with oil-resistant paper, the oil-absorbing water-absorbing paper is incorporated into the inner surface of the oil-resistant paper, so that the oil and moisture from the fried food is absorbed by the inner water-absorbing water-absorbing paper, and at the same time the oil-absorbing water-absorbing paper Oil and moisture absorbed can be blocked with oil-resistant paper, and the oil and moisture can be collected together to properly solve the problems of condensation and condensation while effectively preventing exudation to the outside.

  As a result, the fried food contained in the bag maintains the dry texture and is effective in maintaining quality.

  In addition, the crepe paper is used as an oil-absorbing water-absorbing paper, and an air layer is formed at the interface between the oil-resistant paper and the crepe paper.

  The best mode for carrying out the present invention will be described below with reference to FIGS.

  The object of the present invention is to provide a paper food packaging bag 1 suitable for packaging fried foods such as French fries, fried chicken, hamburgers, croquettes and the like. The main body of the paper food packaging bag 1 is made using oil-resistant paper 2 as a base material. The oil-absorbing and water-absorbing paper 3 is added to the inner surface of the oil-resistant paper 2, that is, the inner surface of the packaging bag in contact with the fried food, thereby forming a bag structure made of a laminated paper of the oil-resistant paper 2 and the oil-absorbing and water-absorbing paper 3.

  As the bag form of the paper food packaging bag 1, as shown in FIG. 1, a bag that opens 11 only at the upper end facing the bag bottom 8, or an opening 11 at the upper end and the upper end as shown in FIG. A bag that opens in an L-shape at one side edge that is connected to is targeted.

  The paper food packaging bag 1 absorbs the oil and moisture from the fried food with the inner absorbent paper 3 and simultaneously blocks the oil and moisture absorbed by the absorbent paper 3 with the oil resistant paper 2. The purpose of preventing the oozing out to the outer surface of the packaging bag 1 is achieved while appropriately solving the problems of bottom accumulation of oil and moisture and condensation.

  The oil-absorbing water-absorbing paper 3 is joined to the inner surface (the inner surface of the packaging bag) of the oil-resistant paper 2 through the starch paste 4 to contribute to food safety.

  As shown in FIGS. 3 and 4, crepe-treated crepe paper 5 is used as the oil-absorbing water-absorbing paper 3, and the crepe paper 5 is joined to the inner surface of the packaging bag 1 (the inner surface of the oil-resistant paper 2). Increase oil absorption and capture effect.

  Preferably, when the oil-absorbing and water-absorbing paper 3 comprising the crepe paper 5 is joined, the crepe peaks 6 and valleys 7 are oriented so as to extend in the lateral direction of the bag (parallel to the bag bottom 8). In other words, the crepe peaks 6 and valleys 7 are oriented so as to extend in a direction intersecting the vertical line of the bag bottom 8 of the paper food packaging bag 1. In other words, the orientation is such that oil or moisture that flows down to the bag bottom 8 is prevented from flowing.

  The orientation of the crepe peaks 6 and valleys 7 improves the effect of absorbing and absorbing oil and moisture from the fried food while being captured by the crepe peaks 6 and valleys 7.

  An air layer 9 is formed at the interface between the oil-resistant paper 2 and the crepe paper 5, and the heat insulation effect is exhibited by the heat insulating effect, and the protective effect against the external force applied to the paper food packaging bag 1 is exhibited.

  That is, as shown in FIG. 3, the crepe paper 5 forming the oil-absorbing water-absorbing paper 3 is shrunk and bonded to the oil-resistant paper 2 with the starch paste 4 with the top surface of the ridges 6. As a result, an air layer 9 is formed by shrinkage troughs 7 at the bonding interface between the oil-resistant paper 2 and the oil-absorbing and water-absorbing paper 3, and the air layer 9 provides a buffering effect and a heat insulating effect for protecting the food.

  The crepe-treated oil-absorbing water-absorbing paper 3 uses paper made of virgin pulp and contributes to food safety. The thickness of the oil-absorbing water-absorbing paper 3 is arbitrarily set, and an oil-absorbing / absorbing function corresponding to the thickness is provided. For example, the oil-absorbing water-absorbing paper 3 having a basis weight per square meter of 30 to 50 g is used.

  The oil-resistant paper 2 used as the paper-making paper for the paper food packaging bag 1 is a paper coated with a conventionally used fluorine-based oil-proofing agent, or coated with the same oil-proofing agent on the surface. Either the paper on which the agent layer 10 is formed or the oil-resistant paper 2 in which a synthetic resin film is laminated on the outer surface of the paper is used. Preferably, the oil-resistant paper 2 is a paper made of virgin pulp as in the case of the oil-absorbing and water-absorbing paper 3.

  In general, the oil resistance of the oil-resistant paper 2 is desirably a kit value (TAPPI UM-557) of 8 or more, which is a level that repels salad oil, and can have any oil resistance. For example, if it has oil resistance of about 3-10, it can respond to existing fried food.

  As the oil resistant agent of the oil resistant paper 2, a known fluorine-based oil resistant agent can be used. Alternatively, in addition to the fluorinated oil proofing agent, an oil proofing agent obtained by mixing one or more of modified starch, amylose, and polyvinyl alcohol can be used. The oil proof agent is impregnated in papermaking, or after paper making, the oil proof agent layer 10 is formed by coating the oil proof agent to form the oil proof paper 2.

  The oil-resistant paper 2 and the oil-absorbing and water-absorbing paper 3, that is, the oil-resistant paper 2 with the oil-absorbing and water-absorbing paper 3 are combined with each other. It has a structure that demonstrates it.
