When doing crafts, you might encounter some small problems, such as only having wide tape at home, but narrow tape is more suitable. In this case, a clever trick can help you solve this problem. It's a great method for handling transparent tape and double-sided tape. Materials needed: Wide tape, utility knife, rubber band, pen.
PE stretch film is an industrial packaging product characterized by high tensile strength, high elongation, good self-adhesion, and high transparency. It can be used for both manual and machine wrapping and is widely applicable for the centralized packaging of various goods. PE stretch film is mainly composed of several different grades of polyethylene resin extruded together. It features puncture resistance, high strength, and high performance.
Transparent adhesive tape was first developed by Richard Drew in St. Paul, Minnesota, USA. On May 30, 1928, applications were filed in both Britain and the United States. Drew had developed a very light, pressure-sensitive adhesive. Initial attempts were not sticky enough, so Drew was told, "Take this thing back to your Scottish bosses and tell them to put in more glue!" ("Scottish" means "stingy").
To deepen everyone's understanding of adhesive tape, I will share my analysis of the three types of adhesives used in tape, hoping it will be helpful: Water-based coating adhesives use water as a solvent to emulsify acrylic or polyurethane resins using specialized emulsification equipment. Their biggest advantages are: wide variety, environmental friendliness, and low price. Many coatings now use water-based adhesives, such as general water-soluble PA, water-soluble PU, as well as film adhesives, oil-feel/wax-feel adhesives, and functional pastes like color pastes. Water-based adhesives, with their functionality, environmental friendliness, and low price, represent the future direction of coatings. Disadvantages include poor film-forming properties, poor wash fastness, and the inability to apply hot melt adhesives to PU.
(1) Coated paper: Excellent printability and low cost; commonly used for large-volume bottle and can labels and outer box labels. (2) VC material: Good waterproof performance and tear-resistant; commonly used for outer packaging labels of products such as shower gel and shampoo.
While people are aware that the cross-sectional area of power cord materials affects electrical safety during electricity use, they often don't pay enough attention to the use of insulating tape at joints. Improper use of insulating tape can cause leakage, endangering personal safety or causing fires. So, how should insulating tape be used correctly? Power cord joints are divided into "+" type, "-" type, "T" type, etc. The joint should be securely wrapped, smooth and free of burrs. Before breaking the wire end, lightly press it with wire cutters, then wrap it around to the opening, and then swing it left and right; the wire end will break off neatly at the joint. If the joint is in a dry place, first wrap it with two layers of insulating black cloth, then two layers of plastic tape (also called PVC adhesive tape), then wrap two or three layers of J-10 self-adhesive insulating tape stretched to about 200%, and finally wrap two layers of plastic tape.
