Why does the adhesive label material bubble?
1. Uneven application of strong adhesive: The surface of self-adhesive label material consists of three parts: surface material, adhesive, and backing paper. The design scheme of the labeling punching machine wheel is poor, and the working pressure is insufficient.
2. Electrostatic effect: For plastic film materials, electrostatic induction can also cause bubbles on the label.
3. Improper speed adjustment and labeling method of the labeling machine: During labeling, the operating speed of the bottle body should be slightly faster than the labeling rate, which can also avoid the occurrence of bubbles.
4. Before labeling, static electricity should be completely eliminated to make the label stand upright and free from the backing paper.
5. Brushes, sponge rollers, and vacuum pumps should not be used for labeling in the labeling machine. A vulcanized rubber scraper with a certain hardness should be installed to touch the label and maintain a certain direction and amplitude of the scraper. The labeling of soft bottles requires adjusting the labeling speed, scraper amplitude, viewing angle, and spacing in between.
What are the characteristics of stickers
1. Small investment, quick results: Adhesive printed products are mostly trademarks and stickers, with small format, fast printing speed, and less production waste.
2. Flexible printing method: Adhesive stickers are not limited by printing methods, and traditional printing factories can use offset or screen printing machines for printing.
3. Multi functional: Adhesive stickers are widely used in food, cosmetics, barcode products, and can also be used as labels for special environments such as electronic and mechanical products.
Adhesive paper structure
1. Coating: corona treatment or printing (printing treatment).
2. Face paper: According to the material, it can be divided into copperplate paper/PET/PVC, etc. The face paper and the back surface are coated with adhesive. Adhesive type: long-lasting adhesive type (strong adhesive type), detachable type (weak adhesive type), readable type.
3. Base paper: Ordinary base paper and Grassin base paper, coated with a silicon oil layer on the surface, which has a barrier effect on the adhesive.
Precautions for using adhesive anti-counterfeiting labels:
1. Before labeling, it is necessary to ensure that the object being labeled is clean, avoiding dust, water stains, oil stains, etc. After attaching the label, it should be flattened and ensure sufficient adhesion
2. The contact temperature and humidity between the label and the object to be pasted should be appropriate, and the appropriate glue and material should be selected, which varies depending on the object to be pasted
3. The label storage environment should be well ventilated, dry, moisture-proof, and maintained at a temperature of 5-30 ℃
4. Unused labels should be sealed and stored, and should be used up within 3 years as much as possible. Prevent the deterioration of glue and coating materials from affecting the effectiveness of use
5. When storing labels, do not stack them too high. Each label should be kept flat to avoid folding and prevent excessive pressure from causing glue overflow, resulting in label adhesion waste
Application fields of adhesive label materials
Packaging industry: shipping labels, postal packages, letter packaging, transportation goods labeling, envelope address labels
Commodity industry: price labels, product description labels, shelf labels, barcode labels, drug labels
Chemical industry: labeling of paint materials, packaging labeling of gasoline and engine oil products, and labeling of various special solvent products
Electronic appliance labels used in the electronic appliance industry: Various types of appliances are labeled with numerous durable adhesive labels, which have a large unit area and a large quantity. In addition, adhesive labels have been widely used as explanatory labels for industrial products (such as computers), which has also driven the demand for adhesive labels
Logistics labels in the logistics industry: In recent years, the logistics industry has been rising in China, and there is an increasing demand for variable information printed labels in modern logistics, such as storage and transportation labels, luggage labels, supermarket labels, etc
Pharmaceutical labeling in the pharmaceutical industry: Adhesive labels are increasingly being used for drug packaging. With the over-the-counter sale of drugs, drug manufacturers and consumers are paying more attention to drug packaging, which will largely encourage drug manufacturers to accelerate the transition from traditional labels to self-adhesive labels
Adhesive stickers are a widely used variety of advertising materials in the advertising industry. They are best paired with instant label engraving machines to create products that are widely used in lightbox, sign making (framing), vehicle advertising, permanent signage, signage, computer cutting patterns, window display patterns, display board production, and many other fields
The back adhesive of this product is an acrylic solvent based pressure-sensitive adhesive with excellent adhesion. It is a polymer rolled polyethylene base adhesive with multiple colors, strong color retention, and uniform color. It has good weather resistance and pollution resistance, good anti shrinkage performance, and a service life of more than three years. It is a cost-effective method for ordinary storefront decoration
Other industries: anti-counterfeiting labels, encrypted labels, anti-theft labels
