Abstract

The utility model discloses a tea bag packaging bag, which comprises a laminar thin film in a rectangular structure. The laminar thin film is divided into an oriented polypropylene (OPP) thin film, an aluminium foil and a polyethylene (PE) thin film sequentially from the outside to the inside, the laminar thin film is folded in a length direction, two side edges are jointed to form a cuboid cavity which has side walls and openings at two ends of the side walls, tea is placed in the cavity, and the openings at the two ends of the side walls enable the cavity to form an enclosed space through heat sealing and vacuumpumping. The tea bag packaging bag is good in sealing effect, excellent in tea fresh-keeping effect and long in preservation time.

Description

The packaging bag of a kind of tea in bag leaf

Technical field

The utility model relates to the tea packaging field, is meant the packaging bag of a kind of tea in bag leaf specifically.

Background technology

Tealeaves is a kind of dry product, and very easily moisture absorption is made moist and produced qualitative change, and it is very strong to the absorption of moisture, peculiar smell, and the fragrance highly volatile.When the tealeaves improper storage, under the effect of the factors such as moisture, humiture, light, oxygen, can cause bad biochemical reaction and the activity of germ, thereby cause the variation of tea quality.Therefore, the packing of tealeaves seems very important.

The packing of tealeaves is mainly divided inner wrapping and gift box packing.Inner wrapping is that the client makes tea for ease, and the inner wrapping that carries out according to quantitative gram number steeps with bag and to pack tealeaves; Existing tealeaves small package bag mainly is to be fitted by cladding material and internal layer membrane to form; This type packaging of tea poor sealing, the tea fresh keeping weak effect, the holding time is short.

The utility model content

The utility model provides the packaging bag of a kind of tea in bag leaf, has shortcomings such as fresh-keeping effect is poor, the holding time is short to solve existing packaging of tea.

The utility model adopts following technical scheme:

The packaging bag of a kind of tea in bag leaf; The laminar film that comprises a rectangle structure; This laminar film is followed successively by OPP film, aluminium foil and PE film from outside to inside, the doubling along its length of layered film, and dual-side is fitted and is formed the cuboid cavity with sidewall and both ends open; Be placed with tealeaves in this cavity, the sidewall openings at two ends vacuumizes through heat-sealing and makes cavity form confined space.

The above-mentioned sidewall that surrounds cavity comprises upper/lower terminal face and and arranged on left and right sides face, and said and arranged on left and right sides face is all inwardly amounted to along its length direction.

More preferably, the above-mentioned heat-seal land that surrounds the sidewall both ends open of cavity is equipped with and can tears the breach that tealeaves is taken out in this packaging bag.

Can know by above-mentioned description, compare the utility model tool with prior art the utility model structure

Following advantage is arranged: the packaging bag of the utility model tea in bag leaf comprises OPP film, aluminium foil and PE film, and this packaging bag is sealed to form through vacuumizing, and removes mould ability because OPP has the sterilization of wide spectrum; And nonpoisonous and tasteless, be anti fouling composition preferably, aluminium foil is soft metallic film; Have advantages such as moistureproof, airtight, shading, erosion resistant, guarantor be fragrant, nonpoisonous and tasteless, with the PE plastics compound after, combine the heat seal property of the shielding of aluminium foil and PE together; Further improved shielding properties to steam, air, ultraviolet ray and bacterium etc.; So the sealing effectiveness of the tea in bag leaf packaging bag of the utility model is better, the tea fresh keeping effect is better, and the holding time is long.

Description of drawings

Fig. 1 is the scheme drawing of the utility model laminar film;

Fig. 2 is the cutaway view in A cross section among Fig. 1;

Fig. 3 is the structural representation of the utility model.

The specific embodiment

The specific embodiment of the utility model is described with reference to the accompanying drawings.

With reference to Fig. 1, the packaging bag of a kind of tea in bag leaf comprises the laminar film 1 of a rectangle structure; With reference to Fig. 2, this laminar film 1 is followed successively by OPP film 11, aluminium foil 12 and PE film 13 from outside to inside, and the sterilization that OPP film 11 has wide spectrum removes mould ability, and nonpoisonous and tasteless, is anti fouling composition preferably; Aluminium foil 12 is soft metallic films; Have advantages such as moistureproof, airtight, shading, erosion resistant, guarantor be fragrant, nonpoisonous and tasteless; With PE film 13 compound after; Combine the heat seal property of the shielding of aluminium foil 12 and PE film 13 together, further improved shielding properties steam, air, ultraviolet ray and bacterium etc.

With reference to Fig. 3; Laminar film 1 doubling along its length; Dual-side is fitted and is formed the cuboid cavity 2 with sidewall 3 and both ends open; Be placed with tealeaves in this cavity 2, sidewall 3 openings at two ends vacuumize through heat-sealing and make cavity 2 form confined space, and the sidewall 3 that surrounds cavity 2 comprises upper surface 31, lower surface and left surface 32, right flank 33; And arranged on left and

right sides face

32,33 is all inwardly amounted to along its length direction, and the heat-seal land that surrounds sidewall 3 both ends opens of cavity 2 is equipped with can tear the breach 21 that tealeaves is taken out in this packaging bag.

Can know that through foregoing description the sealing effectiveness of the tea in bag leaf packaging bag of the utility model is better, the tea fresh keeping effect is better, and the holding time is long.

The above-mentioned specific embodiment that is merely the utility model, but the design concept of the utility model is not limited thereto allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
