Description
Technical field
The present invention relates to barrier container, it is specifically for use in the container for containing food, drug and chemical products.
Background technique
With the improvement of people's quality of life, it is continuous that the requirement that especially food is stored or packed is stored or packed to product
Improve, in order to the guaranteeing the quality of food, it is fresh-keeping, protect flavor and Shelf-life, be developed high-barrier packaging material.
There are three types of blocking methods on the market now:
1. three layers altogether note or multilayer be total to note: three layers note or multilayer are infused all altogether altogether is to be injected with pp (polypropylene) wherein, cover half
After the cooling of two wall of dynamic model, EVOH (ethylene/vinyl alcohol copolymer) is injected to point cooling time, is formed and is obstructed in middle layer.
2. multi-layer co-extruded: being formed and obstructed with aluminizer, barriering effect is higher than EVOH.
The bright IML:PP of jade-like stone 3. (container material quality layer)+cpp (plastics fused layer)+aluminium foil film+opp (being printed in printing layer)；
Side mark: in cover half；
Bottom mark:
1. millimeter paper is placed on mavable module core, millimeter paper is in cup bottom inner portion；
2. millimeter paper is placed on fixed mold core, millimeter paper is outside cup bottom end；
Barriering effect: IML aluminium foil film > aluminizer > EVOH.
Since, there is hydroxyl, EVOH resin has hydrophily and hygroscopicity in the molecular structure of EVOH resin.Work as absorption
After moisture, the barrier property of gas, which will receive, to be significantly affected.In the environment (50%RH or more) of high humidity, the barrier property of EVOH
It declines to a great extent.Aluminizer has excellent folding resistance and good toughness, pin hole and breach seldom occurs, and no flexure cracking is existing
As, therefore the barrier property of gas, water vapour, smell, light etc. is improved., using aluminium foil film, barrier property is more preferable for we, uses
In-mold label plays high-barrier in all directions.
Summary of the invention
It is an object of the present invention to provide a kind of high-obstruction container and preparation method thereof, solves barriering effect in the prior art and pay no attention to
Think or to make barrier material cost too high, is not able to satisfy the technical issues of people require barrier in daily life.
The present invention solves technical problem and adopts the following technical scheme that
A kind of structure of high-obstruction container is divided into 4 layers, including pp (polypropylene) layer, cpp (plastics fused layer), aluminium foil film layer
And opp layers of composition, pp (polypropylene) layer is the raw material as container, and the aluminium foil film layer is as barrier layer, institute
The side that barrier millimeter paper layer is bonded in the aluminium foil film layer is stated, the barrier millimeter paper layer is by printing layer and a small amount of pp (polypropylene)
Layer seamless adhesion composition, meanwhile, the barrier millimeter paper layer has certain barriering effect.
Preferably, the barrier millimeter paper layer is the side for being bonded in the aluminium foil film layer, the other side of the aluminium foil film layer
It is bonded in the pp (polypropylene) layer side, in structure, the aluminium foil film layer is between the pp (polypropylene) layer and the resistance
Between millimeter paper layer, three-decker is seamless adhesion, plays the role of high-barrier；Wherein, the barrier millimeter paper layer by printing layer and
A small amount of pp (polypropylene) layer seamless adhesion composition, a small amount of (polypropylene) layer side pp and aluminium foil film layer side seamless sticky
It closes, the other side of described a small amount of pp (polypropylene) layer and printing layer side seamless adhesion, the other side of the printing layer
It is contacted with air or container product.
Preferably, pp (polypropylene) layer is as container original structure layer, and pp (polypropylene) layer is as raw material
Container of various shapes can be formed, for example plate-like, box-like, cup-shaped, circle, rectangular, diamond shape, asymmetric shape and other abnormity are all
Can be with, the aluminium foil film layer can be bonded in the inside or/and outside of various shape container as barrier layer, including chamber wall,
Container bottom and container cover play the role of high-barrier effect.
A kind of preparation method of high-obstruction container:
Bonding barrier layer method outside chamber wall: from cover half into glue, aluminium foil film, the aluminium are injected to certain point cooling time
Paper tinsel film forms barrier among two layers, and described two layers is pp (polypropylene) layer and barrier millimeter paper layer, patch barrier mark outside chamber wall
Reach exterior circumferential barriering effect.
Container bottom bonding barrier layer method:
S1. mold of putting upside down pastes to paste barrier from container bottom and mark outside bottom end, in injection molding film from cover half into glue to be reached
Bottom barrier.
S2. just putting mold, patch pastes inside barrier mark from container bottom in bottom inner portion, injection molding film from cover half into glue
Reach bottom barrier.
Vessel port bonding barrier layer method: vessel port aluminium foil film sealer, whole container obstruct completely, and it is efficient to save cost
Barrier.
Barrier layer structure is divided into two kinds of situations from the inside to surface, the first be sequentially followed successively by pp (polypropylene) layer, aluminium foil film layer,
Millimeter paper layer is obstructed, second of sequence is followed successively by barrier millimeter paper layer, aluminium foil film layer, pp (polypropylene) layer, and injection molding barrier is integrally formed
Efficient high-barrier.
The invention has the following beneficial effects:
Barrier mark uses aluminium film, and aluminium film has splendid metallic luster, and light reflectivity can pass through coating up to 97%
Processing formation colour film is more good-looking by product appearance, and sealing property is good, when especially packing powdery product, will not pollute sealing
Part ensure that the sealing performance of packaging.It is high to be integrally formed at low cost and barrier property, Food Oxidation can be delayed rotten existing
The generation of elephant greatly prolongs shelf life, while the fragrance that can be avoided content is lost and prevents external bad smell
Intrusion, and gas barrier properties do not change with the variation of humidity, will not cause product rotten high humidity environment, can prevent
There is a phenomenon where dehydration exsiccation, taste bad for product.It is efficient that the saving cost savings time is integrally formed with patch injection molding barrier in mould
High-barrier.
