How to remove the inkjet code on the plastic bag packaging?

the following methods can be used to remove the inkjet date on the package:

1 Isoamyl acetate

isoamyl acetate, commonly known as banana water. It is mainly used as solvent and diluent for painting. Use a cotton swab dipped in a small amount of banana water to smear the spray code, and wipe it with a rag or paper towel

2. Dimethyl ketone

dimethyl ketone, also known as acetone, is mainly used as a solvent in industry in industries such as explosives, plastics, rubber, fiber, tanning, grease, painting and so on. Use a cotton swab dipped in acetone to smear the code, which can also be wiped off
> the thinner and the thinner used in the packing machine are highly flammable. Br>> Please note that the thinner and the thinner used in the packing machine can be used to remove the irritation. Br>> Please note that the thinner and the thinner used in the packing machine must be used for cleaning

for some packaging materials such as paper, the ink can not be erased when it penetrates into the interior

the inkjet date on the commodity package cannot be removed. What the laser inkjet printer sprays is a permanent mark that cannot be erased. It is formed by instant gasification of the laser directly on the object surface. It can be distinguished by the naked eye without the help of any auxiliary tools, which is convenient for consumers to identify. And no consumables, more convenient maintenance. Laser inkjet printer breaks through the standardization and singleness of traditional ink inkjet technology, creates a new injection mode, highlights the characteristics of products and brand differences, improves the competitiveness of products in the increasingly fierce market, and provides a powerful tool for shortening the upgrading cycle of products and flexible production.

first of all, we need to know the specifications of the purchased carton, such as pit type, gram weight of paper, burst resistance of carton, edge pressure of carton and other important parameters, among which burst resistance and edge pressure are very important, because this will involve the paper matching specifications of paperboard, so why there are different quality differences for the same type of paper. Here are some basic knowledge of cartons for your reference:

then, the supplier will provide the corresponding square price or thousand square feet price according to the specifications you provide. Then we can know the price of cartons as long as we know the area of cartons we use. Various forms of calculation formulas we see are processed through this principle, Knowing this, we can better understand when facing the formula

taking the price of 1000 square inches as an example, the corrugated box uses the following calculation formula:

(unit cm): [(length + width) /2.54 + 2] * [(width + height) /2.54 + 1] * 2 * unit price /1000

if the box type changes, the above formula cannot be used. Is there a formula that can be used for all box types? Of course, we can get the following universal calculation formula by multiplying the area by the unit price:

(length /2.54 + 1 “) * (width /2.54 + 1”) * unit price of 1000 square inches * /1000

note that in the above formula, both length and width are the maximum unfolding size of the carton, and adding 1 inch each is the flash left

take a simple flat card as an example. Its expansion size is its own length and width. If the size is directly substituted into the above formula, the flat card price will come out. Do you understand? Is it very simple

the price calculation method of the color box is much more complicated. If you want to know, you can pay attention to the official account of the purchase note. Oh, I will sort out the

for you first. We need to understand the cardboard specifications such as pits, paper weight, carton bursting, side pressure of the paper box, etc. the breakage and side pressure are very important, because this will involve the paper distribution specification of the cardboard. So why do the same type of paper have different quality differences. Here are some basic knowledge of cartons for your reference:

the plastic recycling sign is a triangular symbol, usually at the bottom of the plastic container. There are 1 ~ 7 numbers in the triangle, and each number represents different materials. Therefore, different numbers in the recycling sign indicate which resin the product is made of. If the product is made of several different materials, it indicates the main and basic materials of the product. It is said that this set of signs originated from the United States. Now this marking method has been accepted and cited by many countries, including China. In China, it is not mandatory for plastic products to mark recycling marks. In order to facilitate the recycling of plastic products, some formal large brand enterprises have recently begun to mark recycling marks. Although this sign is mainly for recycling, consumers can also know what material the plastic products are made of and under what environment they should use.

the use conditions of different materials are different

the small recycling logo at the bottom of plastic products is like a small ID card of each plastic container. They are made of different materials and used differently.

“01” — PET (polyethylene terephthalate)

common uses: mineral water bottles, carbonated beverage bottles, etc.
mineral water bottles and carbonated beverage bottles are made of this material. The beverage bottle cannot be recycled to contain hot water. This material is heat-resistant to 70 ℃, and is only suitable for warm or frozen drinks. If it is filled with high-temperature liquid or heated, it is easy to deform and dissolve substances harmful to human body. In addition, scientists found that after 10 months of use, this plastic product may release carcinogens and be toxic to human body. Therefore, drink bottles should be discarded when they are used up. They should not be used as water cups or storage containers to hold other items, so as not to cause health problems
pet was originally used as man-made fiber, film and tape. It was only used in beverage bottles in 1976. Using PET as raw material as filling container is commonly known as “Baote bottle”. Baote bottle has excellent hardness and toughness, light weight (only 1 /9 ~ 1 /15 of the weight of glass bottle), convenient carrying and use, low energy consumption during production, and is a good packaging material for carbonated drinks due to its airtight, non-volatile and acid and alkali resistance. In recent years, it has become an important filling container for carbonated drinks, tea, fruit juice, packaged drinking water, wine and soy sauce. In addition, Baote bottles have been widely used, such as detergent, shampoo, food oil, condiment, sweet food, medicine, cosmetics and packaging bottles of alcoholic beverages

“02” — HDPE (high density polyethylene)

common uses: cleaning products, bath products, etc.
plastic containers for cleaning products and bath products. At present, most plastic bags used in supermarkets and shopping malls are made of this material, which can withstand 110 ℃ high temperature. It is indicated that plastic bags for food can be used to contain food. Plastic containers containing cleaning products and bath products can be reused after careful cleaning, but these containers are usually difficult to clean, leaving the original cleaning products and becoming a hotbed of bacteria. If the cleaning is not complete, it is best not to recycle them
PE is the most widely used plastic in industry and life. It is usually divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE). PE has excellent resistance to acid and alkali. HDPE has higher melting point and hardness than LDPE, and is more resistant to the corrosion of corrosive liquids. At present, almost all plastic bags and all kinds of translucent or opaque plastic bottles seen in the market are made of PE, such as detergents, shampoo, shower gel, edible oil, pesticides, etc. most of them are contained in HDPE bottles. LDPE is ubiquitous in modern life, but it’s not the container made of it, but the plastic bag you can see everywhere. Most plastic bags and plastic films are made of LDPE

“03” — PVC (polyvinyl chloride)

common uses: raincoats, building materials, etc.
it is reported that the toxic and harmful substances easily produced by this kind of plastic products come from two aspects: one is the monomolecular vinyl chloride that has not been fully polymerized in the production process, and the other is the harmful substances in plasticizers. These two substances are easy to precipitate when encountering high temperature and oil. After the toxic substances enter the human body with food, they are easy to cause cancer. At present, the containers of this material have been less used to package food. If in use, do not let it be heated
PVC was invented quite early and widely used in industrial products. Because PVC also has the advantages of other plastic materials, and is quite excellent in processing and plasticity. In addition, it is cheap and widely used, but most of it is in non food aspects, such as water pipes, raincoats, schoolbags, building materials, plastic films, plastic boxes and so on. In terms of container use, it is mostly used to fill vegetable oil, detergent, cake box and package drinking water. Because the material itself contains chlorine, it is suspected that VCM monomer is easy to release in the process of bottle making, filling, recycling and reprocessing, which is likely to endanger human health. In addition, with the rising awareness of environmental protection in recent years, the industry has gradually changed to other materials to fill containers

“04” — LDPE (low density polyethylene)

common uses: fresh-keeping film, etc.
fresh-keeping film and plastic film are all made of this material. Poor heat resistance,
