Choose the Right Adhesive: Making Packaging Both Beautiful and Durable The aesthetic appeal and durability of printed packaging hinge on a crucial—yet often overlooked—element: the adhesive used. From the everyday shipping boxes and food packaging we receive, to high-end gift sets for tobacco and spirits, every bonded joint relies on the support of specialized adhesives. Selecting the right adhesive not only prevents embarrassing issues such as delamination and seam separation, but also ensures compliance with environmental standards, boosts production efficiency, and can even help reduce costs. Adhesion Applications 01 Bonding Adhesives Laminating processes are primarily utilized for applications such as paperboard mounting for cartons, gift box assembly, and label application. The core requirements are strong bonding strength and rapid drying speeds, while simultaneously balancing environmental sustainability with ease of operation to prevent issues like weak adhesion or bond failure. 02 Box Sealing Adhesives Carton sealing adhesives are primarily used to seal shipping boxes and corrugated cardboard cartons. The core requirements include robust bonding strength and impact resistance, along with the ability to withstand diverse transport environments (including high temperatures, low temperatures, and high humidity), all while maintaining high production efficiency and environmental friendliness. Specialty Application Adhesives As the printing and packaging industry evolves toward higher-end and more functional applications, the demand for specialty adhesives is steadily rising. These adhesives are specifically formulated to accommodate packaging made from unique materials or utilizing specialized manufacturing processes, thereby meeting the most rigorous performance standards.

Classified by Raw Materials Vinyl Acetate Latex Paint Vinyl acetate latex paint refers to a category of latex coatings produced from polyvinyl acetate emulsion, combined with pigments, fillers, and various additives. This type of coating features strong adhesion, good flow properties, and low production costs. However, it is characterized by high brittleness, necessitating the addition of external plasticizers. It is also prone to hydrolysis, exhibits poor chemical resistance, and lacks alkali resistance. It is generally utilized as an interior architectural coating. Ethylene-Vinyl Acetate (EVA) Latex Paint Ethylene-vinyl acetate (EVA) latex paint is primarily used in architectural coatings. It is suitable for flat exterior wall surfaces and is classified as a type of polyvinyl acetate-based latex paint. Acrylic Latex Paint Acrylic latex paint is typically produced from acrylic emulsion, blended with pigments, fillers, water, and various additives. Acrylic latex paint offers comprehensive and superior performance, featuring excellent adjustability in properties and the advantage of releasing no organic solvents. It possesses high initial gloss, outstanding gloss and color retention, excellent outdoor durability, as well as good resistance to staining, alkali, and scrubbing. It can be formulated into various interior and exterior latex coatings, ranging from high-gloss and semi-gloss to flat finishes. Acrylic latex paint is moderately priced and enjoys extremely widespread application. Styrene-Acrylic Latex Paint Latex paint produced from a styrene-acrylic (ester) copolymer emulsion is known as styrene-acrylic latex paint. This category of coating features excellent resistance to weathering, water, and alkali, as well as strong resistance to chalking and staining. By substituting styrene for all or part of the methyl methacrylate typically found in pure acrylic emulsions, this product achieves cost reductions while maintaining performance levels comparable to pure acrylic latex paints. Classified as a medium-to-high-grade interior architectural coating, it exhibits excellent adhesion to cement substrates and superior scrub resistance. Suitable for use in areas with high humidity, it currently stands as one of the dominant varieties of interior wall coatings in China. Vinyl Versatate Paint Vinyl versatate paint is a type of latex paint based on a copolymer of vinyl versatate. The vinyl versatate monomer features a bulky, highly branched tertiary carbon group that acts as a protective shield for the polymer backbone while simultaneously providing an internal plasticizing effect. Consequently, vinyl versatate paints deliver exceptional film performance, characterized by outstanding durability, aesthetic appeal, ease of application, and superior environmental and health credentials; they are formaldehyde-free and exhibit extremely low VOC levels. These paints possess robust resistance to both water and alkali; the resulting paint film is fine-textured...

Many people find themselves torn when selecting materials: since both are used for coatings, which one offers greater durability? Which is the more suitable choice for waterproofing during renovation? In reality, neither possesses an absolute advantage over the other; the key lies in the specific requirements of the application scenario. Today, we will clarify the core distinctions between the two—from their fundamental chemical nature to their practical applications—once and for all. I. Chemical Nature: Two Fundamentally Different "Molecular Architectures" The core difference between these two materials stems from their molecular structures, which, in turn, determine their fundamental performance characteristics: Polyurethane: A class of polymer compounds featuring a main chain containing unique urethane linkages. Its molecular structure can be flexibly engineered by adjusting the ratio of polyols to isocyanates, allowing it to act like a "Transformer"—shifting between the properties of a soft elastomer and a rigid plastic. Depending on the specific type, it is further categorized into aliphatic (resistant to yellowing) and aromatic (prone to yellowing) varieties, each exhibiting distinct performance profiles. Acrylic: Features a main chain consisting of long carbon-carbon chains derived from acrylate esters. Its core functional groups are double bonds and carboxyl groups, endowing it with high chemical reactivity. It can be polymerized—either through homopolymerization, copolymerization, or light/heat-initiated curing—to form polymeric materials. Acrylic products come in a wide variety of forms—including water-based, solvent-based, and UV-curable types—making them adaptable to diverse environmental standards and construction requirements. II. Core Performance Showdown: Each Excels in Specific Areas Performance (polyurethane) PU (acrylic) AC Hardness and Toughness Extremely wide range, wear-resistant and impact-resistant Medium to high hardness, moderate toughness, prone to brittleness at low temperatures Weather Resistance Aliphatic compounds exhibit excellent yellowing resistance, whereas aromatic compounds are prone to yellowing. UV-resistant, with excellent gloss and color retention; resistant to chalking Adhesion The polar urethane bond is compatible with a wide range of substrates, particularly plastics and rubber. Offers good versatility, but exhibits relatively weak adhesion to non-polar plastics Chemical Resistance Resistant to oil and dilute acids/bases; aliphatic varieties demonstrate superior performance. Weak solvent and alkali resistance Environmental Safety High-quality products are eco-friendly, whereas inferior tar-based products emit toxic odors. Water-based technology is mature, features low VOCs, and is non-toxic and odorless. III. Application Scenarios: Choosing Wisely to Avoid Waste Performance differences directly define the boundaries of application; these two classes of materials collectively cover a vast spectrum of nee...

Water-based acrylics and oil-based acrylics are two distinct types of acrylics. But do you know what distinguishes them? Base Water-based Acrylic: The base for water-based acrylics is water. It is an acrylic coating that utilizes water as its solvent. Oil-based Acrylic: The base for oil-based acrylics consists of acrylic resins suspended in organic solvents. Drying Time Water-based Acrylic: Water-based acrylics have a relatively fast drying time, typically drying within a few hours. Oil-based Acrylic: Oil-based acrylics have a longer drying time; they may require several days or even longer to dry completely. Odor and Volatility Water-based Acrylic: Water-based acrylics have a mild odor and low volatility, making them relatively environmentally friendly. Oil-based Acrylic: Oil-based acrylics contain organic solvents, resulting in a stronger odor and higher volatility. Cleaning and Dilution Water-based Acrylic: Water-based acrylics can be cleaned and diluted using water. Oil-based Acrylic: Oil-based acrylics require the use of organic solvents for cleaning and dilution. Peelability Water-based Acrylic: Water-based acrylics perform relatively well in terms of peelability; the coating is easy to peel off. Oil-based Acrylic: Oil-based acrylics perform poorly in terms of peelability; the coating is difficult to peel off. It is worth noting that water-based and oil-based acrylics are suited for different application scenarios. Water-based acrylics are commonly used for interior paints and eco-friendly coatings, whereas oil-based acrylics are typically used for exterior paints and applications requiring higher durability.
