Product Description:

Product name: Induction seal liner for plastic and glass bottles


 1. Introduction


Induction lining materials are one of the most important parts in packing industry for sealing the bottles and containers of the products for many reasons. And induction sealing is a simple and reliable method of bottle sealing. It welds an aluminum foil seal across the bottle neck.


 2. Main specifications:

 - Aluminum foil = 20-40 microns (0.02 - 0.03 mm)

- PE/PET/PP layer = 40-50 microns (0.04 - 0.05 mm)

 - Seal backing material: pulp, foam, cardboard;

- Easy peel and non-easy peel seal available;
- Seal diameters are available from 10 mmto 180 mm;


- With different composition, liner thickness is various from 0.2mm to 1.2mm;


- It can be printed with custom logo, or embossed with any desired design;

 3. Main benefits:


- Seals in freshness


- Prevent costly leaks


- Reduce the risk of tampering, pilferage, and contamination


- Extend shelf life


- Create hermetic seals


- Environment friendly


 4. They can be used for sealing & packing in the different industries, including:

1- Motor, Engine, and Lubricant Oil products
2- Edible Oil products
3- Medicine products (Pharmaceutical factories for Tablet, Gel, Cream, Powders, Liquids, etc)
4- Food Products
5- Beverages, Fruit Juice, Butter, Honey, Mineral Water
6- Pesticides, Fertilizers, and Chemicals
7- Cosmetics


 5. How to use:

Induction lining materials are constructed from aluminum foil membranes, coated with polymer and attached to a backing material by means of wax or polymer bond.  This foil laminate is then placed inside a cap or closure, and the closure applied to the container, bringing the foil laminate into contact with mouth of the container.
The container then passes underneath the induction sealing head, where an electromagnetic field creates a low level of localized heat on the foil membrane, which is sufficient to melt both wax bond and polymer coating.
Soon after the container leaves area of the electromagnetic field, the polymer hardens, forming a flexible, yet hermetic seal between foil and neck of the container, while the backing material goes inside the cap as interior liner for more protection

Q:which kind of abraser should be used for deburring of aluminum sheet?
you can use soft resin grinding stone.
Q:Which kind of glue can bond hard shell plastic and iron sheet or aluminum sheet?
You can buy the glue for bonding wood in hardware shop, 402 or 502 are all ok.
Q:what's the size of gap while pressing 6mm aluminum sheet?
unilaterial gap is 0.1-0.15mm, and you can change the gap according to cutting effect.
Q:will it influence powder injection effect after wiping the oil contamination on the surface of aluminum sheet?
It’s possible, there are several problems: 1, workers won’t wipe it thoroughly and fully, so you can wipe it after soaking. 2, the wiping efficiency is low, and we can use ultrasonic to clean it. 3, the water is poisonous and harmful to environment and workers’ health, so you can use water base to clean it, environmental and non-poisonous. Of course, if you really want to change, you can use detergent special for aluminum materials cleaning of our company, Changlvfeng chemical industry company. a, its PH value is 6.8-7.2 and it is totally an neutral liquid. b, good material applicability, detergent invented for aluminum materials. c, good degreasing ability, it has a good degreasing function for various oil contamination in processing and has no effect on material.
Q:Which kind of material does aluminum sheet(aluminum oxide) belong to?
it's metal and belongs to hardware
Q:who knows the ceiling technology of aluminum sheet?
Construction technology of ceiling aluminum sheet: (1) firstly check keel’s quality, the straight shape and uniformly forced state of boom, control the keel’s gap within 500mm, reduce the gap according to design requirement under humid environment. The lower surface of keel is smooth without a sense of bearing down, main device is closely connected with accessories, it can be bound after being confirmed qualified.(2) we should break the board along the cutting line and ensure the margin of cutting board straight and square without any chipping or arris defect. (3) while placing and fixing the board, we can place edge of aluminum-plastic panel(encapsulated edge) in the vertical direction of supporting keel, there is a phenomena of hanging. Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. You can start from a plate angle or middle position, and don’t place them at the same time. Slab joint should be straight and in the same width, without break joint. (4) in the process of joint, Aluminum-plastic panel should be placed closely in the process of butt joint, it can’t be pressed. And the butt joint should be stagger, the butt joint can’t be connected on the same keel. When you use doubling plate, the joints of the second layer board and the first layer board can’t be connected with the same keel, double-deck gypsum board should be staggered joints.
Q:What's the standard thickness of aluminum sheet?
the thickness of tobacco aluminum foil and red wine bottle cap is designed according to customers demands and manufacturer has no stated specification.
Q:could magnet attract iron with the seperation of rubber and aluminum sheets?
no problem.
Q:As for cast aluminum sheet or wrought one, which one has faster heat conduction?
1,duralumin: it's the alloy of aluminum, copper, magnesium, manganese and other metals. it's suitable for compacting by rolling, and it has a higher strength and hardness than common aluminum products. 2, aluminum: it contains many inpurities, is crisp and easy to be smashed.cast aluminum usually is secondary aluminum, and it is produced by remelting the collected old aluminum pots and spoons.3, wrought aluminum: it contains 98% aluminum and 2% or more inpurities, and is comparatively pure aluminum. its soft priority makes it suitable for being pressed into various shapes, aluminum pots,aluminum lunch box,aluminum sheets,aluminum wires,aluminum pipes are all made by wrought will know their defferences from their definition.
Q:after putting aluminum sheet into the area between magnet and iron products, could magnet attract iron again?
magnet can attract iron if the aluminum sheet isn't too thick. Because aluminum can't cut off magnetic line of force, unless aluminum sheet's thickness surpass the range of magnetic attraction.
