Carton sealing tape option

We all know tape for carton sealing machine is, how do you buy sealer tape? When choosing the tape what to be aware of it? Just choose a good tape to ensure our grooming box, ensure our sealing effect:
Sealing machine after purchase, but many people worry not because of tape problems, some tape manufacturers to increase the thickness of the paper tube, some add impurities to the tape, and even exaggerate the use of tape length.
Sealing machines are commonly used in packaging equipment, in particular in the carton packaging process is frequently used, directly related to the effect of sealing of the tape, also affect the service life of the sealer, so sealing tape selections are also very important.
1. smell the taste of the tape, as some unscrupulous manufacturers to increase the whole roll of tape thickness and cost savings, increased at impurities, if tape is very strong, even sour, suggesting that tape is likely to join the impurities or toxic substances, prolonged exposure can harm people's health. And retention of this tape is very poor. Tape rubber surface appears dry quickly, losing rubber, performance tape surface is cracked.
2. and then watch the film thickness and brightness. To select tape thin, good tape of selected films are relatively soft, good elongation by the hand, film hard tape is time, and because the film thickness, actual number of meters will be reduced. Higher brightness the tape quality is usually better, fracture probability would be much lower.
3. belt color. Under normal circumstances, Scotch tape look more white, tape-less impurities, high viscous yellow tape to tape with no irregular white spots on the surface, wipe it away with his hand generally of poor quality.
4. the thickness of the paper tube. To use thinner paper tube tape, bore diameter is generally unified 7.6cm, some manufacturers will increase the thickness of paper tubes to mislead consumers.
In short, tape chosen to err, don't bother just buy several rolls of duct tape or cheap low price products, or accelerated depreciation for a sealer is not worth it. Accessories in the sealing machine we want to choose the right accessories, maintenance of our machines to ensure our packaging, our most efficient complete sealing work.
As manufacturer of the sealer, Meg xiaobian recommended to shop around when you buy, do not covet cheap price, to ensure good quality.

Let's look at a public by the General Administration of customs classification decision classification decision number: Z2008-136
Name: double-sided tape
Product description: the product consists of four layers, material composition, from top to bottom are: release paper layer, adhesive layer, acrylic foam substrate layer, adhesive layer, and so on. Foam in the middle with absorption of dissipation energy substrate, buffer, dispersing the longitudinal shear stress, reduce the long-term stress of adhesive joints and so on. Main sealed with adhesive electronic components, auto parts, and so on.
Classification decision: in accordance with general rule number one and six, "two-sided adhesive tape" should be classified in tariff lines 3919.9090.
See the classification decision, the reader may ask, why is "tape", the main features are "sticky", why "cellulose wadding" as base materials classified in heading 3506, substituting "polyacrylate foam" (plastic) base are classified in heading 3919?

The answer is actually very simple, we are going to "cellulose wadding" substrate "tape" classified in heading 3506 is based on the general rule, according to "tape" main functions-"glue" are classified. And the General Administration of Customs will be "polyacrylate foam" substrate "tape" classified in heading 3919 is based on "general rule," instead of using the General rules. Issued by the General Administration of customs for the goods classified opinions, what part does not take into account the main function. But just based on the General rules, it made a clear classification for the goods. In other words, the General Customs Administration based solely on "heading chapter article and a class note or notes" had already determined the tax identification number of the goods.

This product is "paper tape", with high adhesion, with light resistance, aging resistance and heat-resistance. The metals, plastics, cardboard, fabric, leather and rubber, have a higher strength of adhesion, are widely used in communications, electronics, home appliances and other industries. This product with cellulose wadding base, made of acrylic adhesive coating on both sides. On the surface, consistent with the heading notes on interpretation--headings 4811 "single-sided or double-sided in part or in whole with kaolin or other inorganic substances, surface coating materials other than paper, paperboard, cellulose wadding and webs of cellulose fibers", seems to be classified in heading 4811.
However, if further analysis can be found. This product is called "paper tape", that in accordance with the General logic, its main functions will be "glue". In this product, as substrate material for "cellulose wadding" only play a role in strengthening and backing, does not have "bonded" function, in other words, do not constitute the basic features of this product. Acts as a true "glue" effect, apparently "cellulose wadding" coating on the "Acrylic adhesives".
So, according to the general rule of three (two), this product should be "material or component constitutes basic characteristics of goods classified", that is, according to
Is to "glue" effect "acrylic adhesive" classified in heading 3506 (tariff 10%).
In General, reporting "tape" when such goods, whether or not the product is based on cellulose wadding or textile fabrics (for example, non-woven fabric) as substrate, as long as the adhesive coating on the surface and the coating of adhesive material up to the product's main role, according to "glue" classified under heading 3506. Four, by analogy:
After the presentation, I believe readers have to "tape" classification methods have an understanding. So, imagine if this "double-sided tape" of the base material is not "cellulose wadding" instead of "plastic", whether it was related to "glue" classified in heading 3506.

By a large number of gas pore foam dispersed in a solid plastic to form a class of polymer materials, with light, heat insulation, sound absorption, shock absorption and other properties, and dielectric properties superior to the matrix resin, it is widely used. Almost all kinds can be made of plastic foam, foam molding has become an important field of plastic processing. Structural foam 1960s developed to foam core, the cortex is characterized by non-foaming, hard and tough outer, (strength per unit mass) high specific strength, material consumption province, increasingly used in place of wood used in construction and furniture industries. Polyolefin chemical or radiation cross-linked foam technology to succeed, so that the foam has significantly increased yields. After blending, filling, such as modified plastics reinforced foam obtained had a better overall performance, to meet the needs of various special purpose. For example, by reaction injection molding of glass fiber reinforced polyurethane foam has been used as structural components in aircraft, automobiles, computers and the like; and hollow glass beads filled polybenzimidazole prepared foam, light and high temperatures , it has been used in spacecraft. Classification

Micropores communicating between each other is called the open-cell foam, closed cell type called each other a closed foam. A hard foam, a soft two kinds. According to the US Society for Testing and Materials standards, at a temperature of 18 ~ 29 ℃, the time within 5s, about 2.5cm diameter round bar one week, if not broken, test samples are soft foam; otherwise be a rigid foam . Foam can be divided into two types of low foaming and high foaming. Typically the expansion ratio (ratio of the foam after foaming front volume increases in multiples) is less than 5 known as low foaming, high foaming called greater than 5.

First, the rigid foam that is at room temperature to form the polymer foam is a crystalline or amorphous form, their glass transition temperature above room temperature, therefore, at room temperature foam hard texture.

Polyethylene pre toughness, dielectric properties and excellent resistance to chemical corrosion, molding process is good, but poor rigidity, less smoke when burning, low-pressure polyethylene temperature up to 100 ℃.
As a white waxy translucent polyethylene material, soft and tough, is lighter than water, non-toxic, it has excellent dielectric properties. Flammable and away from the fire continues to burn. Polyethylene low permeability, organic vapor transmission rate is larger. The transparency of the polyethylene increases with the degree of crystallinity decreased in a certain degree of crystallinity, transparency and increase with increasing molecular weight. High density polyethylene melting point in the range of 132-135 ℃, low density polyethylene low melting point (112 ℃) and wide range.
At room temperature, not soluble in any known solvent, a small amount of more than 70 ℃ dissolved in toluene, amyl acetate, trichlorethylene and other solvents.

Polyethylene has excellent chemical stability, resistance to room temperature, hydrochloric acid, hydrofluoric acid, phosphoric acid, formic acid, amines, sodium hydroxide, potassium hydroxide and other chemicals, sulfuric acid and nitric acid has a strong role in the destruction of polyethylene . Polyethylene easy photo-oxidation, thermal oxidation, ozone decomposition, prone to degradation under the action of ultraviolet light, carbon black polyethylene has excellent light shielding effect. That can occur after radiation crosslinking, chain scission, form an unsaturated group and so reflect. Polyethylene Classification and Application.
