Cleaning method for adhesive labels
1. First, tear off the adhesive decorations attached to the glass or product surface, soak the towel in warm water (hot water should be used in winter), and repeatedly wipe the adhesive marks twice; Then use a warm and damp towel with soap, and repeatedly wipe the marks several times; Finally, use a clean and warm towel to wipe off the soap foam, and the adhesive marks will be removed
2. Apply toothpaste evenly on the surface of the sticker, let it sit for a while, and then wipe it with a soft cloth. Sometimes there are more stickers and they are more firm. Just apply toothpaste on the traces that have not been removed in one go. The method is still the same, and you can remove the headache sticker. The principle is that toothpaste contains glycerin, which is a good solvent that can dissolve the components of stickers. In addition, many cosmetics also contain glycerin, which can be used to remove stickers
3. Furthermore, using a pen, paper, or knife to scrape, it is suitable for hard surfaces such as glass and floor tiles; Wipe with alcohol, suitable for glass, floor tiles, clothing, etc; Freezing, once the adhesive becomes hard after freezing, it can be directly peeled off and is suitable for methods that are not suitable for alcohol or scratching
4. I heard that the effect of wind oil essence is also good. If it is a self-adhesive sticker or the like, it can be easily peeled off by blowing it with a hair dryer. However, it is not suitable for plastic, as overheated plastic will deform
5. Using a wind dryer to heat blow is very effective and convenient at home. Almost everyone has a wind dryer, whether it is for sticker glass, plastic, wood, or metal. First, use a wind dryer to heat blow back and forth a few times, then tear a small edge and slowly tear along the direction of tearing while using the wind dryer to heat blow. The effect is very good
6. Rub vigorously with a rubber a few times
7. In industry, wiping with natural water is very easy to remove
Adhesive label printing
Small adhesive labels are often an important reflection of a company's image and brand, playing a crucial role in showcasing product quality and arousing consumer desire to purchase. So, when choosing labels or self-adhesive labels, how can the printing process of self-adhesive labels avoid the occurrence of adhesive residue
1. For cylindrical bottles, especially those with a diameter less than 30MM, careful selection of materials is necessary.
2. If the label size is too large or too small, attention should be paid to conducting actual tests.
3. If the object being pasted is an irregular surface or even a spherical surface, there are specific considerations for the type, thickness, and adhesive of the label material.
4. Some rough surfaces such as corrugated cardboard boxes can affect labeling, and the gloss on the surface of corrugated cardboard boxes can also have an impact.
5. Automatic labeling machine labels, and labeling tests can be conducted if necessary.
6. Even if the label is labeled at room temperature, attention should be paid to whether it has experienced high temperatures during export transportation and use.
7. The characteristics of adhesives can be affected by environments with high water or oil content, and attention should be paid to the environment and temperature for label labeling.
8. Sometimes plasticizers may seep out from the surface of soft PVC, so special attention should be paid to selecting the appropriate adhesive.
How to choose adhesive label printing
Color printing of self-adhesive labels is commonly used for mid to high end color printed paper boxes, color boxes, color brochures, photo albums, color pages, books, periodicals, monthly magazines, product labels, self-adhesive printing, various high-end paper bags, paper product imports and exports, color packaging boxes, posters, advertising brochures, gift bags
1. Material Characteristics
PVC material has good plasticity and weather resistance, so it can be used in the printing, food packaging, and toy industries; LDPE/PET materials have good transparency and are suitable for surface decoration of most products; In addition, due to its good chemical resistance, LDPE is suitable for use in electronics, electrical instruments, and automobiles; LDPE/PET can be used to make labels in various shapes. Suitable for printing on various paper and other materials, and can also be used to make the surface of soft products; So when using PE material to print labels, adhesive label printing manufacturers generally choose double-sided printing; Label products are mainly used in the field of food processing, especially in dairy products, meat and other foods; In addition, due to the fact that PE material does not contain volatile components, has low heat resistance, is inexpensive, and has good plasticity, it is widely used in various plastic containers; So economically speaking, plastic products are still widely used
2. Printing methods: Die cutting and embossing inks and printing methods:
① Die cutting method: This is the most commonly used method. The products that need to be printed are die cut on the same sheet using smaller network cables. Due to the fact that the ink required for die-cutting is a liquid emulsion, its production efficiency is high and the quality is stable
② Embossing, also known as relief printing, indentation printing, or screen printing. Its specific method is similar to die-cutting, but its characteristic is that the printing plate is directly printed on the surface of the object, but it requires a certain pressure to be applied to the substrate, generally between 10-20 mm. Imprint ink mainly includes ordinary ink, special pigments, and organic pigments (all three main pigments have certain functions during use); But generally speaking, the pigments contained in ink have a certain adhesion to the surface of the printing plate, and the pigments in the ink will disperse on the paper and adsorb onto the printing plate. So there are high requirements for these factors, and the ink used should not be too much or too thick. Printing that requires cleaning and drying in the air for a period of time after printing before wiping is called die cutting
Usually, a scraper is used to scrape off the surface of a piece of paper to obtain the desired printing plate content. For special occasions where there are no special requirements for ink, solvent-free ink (excluding solvents) can also be used for printing, such as transparent films and other inks that have a certain affinity for various organic solvents in the ink (such as polyvinyl alcohol or polyamide), and inks made in solvent-free ink without solvents (such as benzene resin, ethyl acetate, etc.); Sometimes solid solvents or water are used as the base ink to achieve surface printing of a special material formed on the adhesive surface, as well as other ink printing methods with special requirements. This type of ink has certain environmental requirements, such as non corrosiveness, heat resistance, printing adaptability, and non water absorption, all of which should meet the required conditions; It can also be directly printed after die-cutting that is similar to the appearance of the product; Direct embossing can also be used for printing. Die cutting ink does not contain solvents or additives (such as water, solvents, petroleum, etc.). Organic solvents do not contain solvents (such as benzene, styrene, etc.), volatile substances such as organic solvents, and oxidants; Belonging to harmful substances of organic solvents
What are the characteristics of kraft paper adhesive labels?
