I.Characteristics of Paper-Plastic Composite Packaging Materials Paper-Plastic Composite Packaging Materials As end-consumers increasingly demand visual impact and packaging perfection from various brands, as well as a focus on environmental sustainability, many brands are incorporating more paper elements into their packaging designs. Fruit gift boxes, snack bags, and medicine boxes all feature p...
The adhesive (glue) used in self-adhesive labels is a key factor in determining label performance, directly affecting the adhesive's adhesion, durability, and application scenarios. Different glue types are suitable for different materials, environments, and applications. This article will introduce the types and characteristics of self-adhesive label glues, as well as factors to consider when sel...
In label production, whether choosing oil-based, water-based, or hot melt, sufficient initial tack is required. Adhesives with strong initial tack properties can easily adhere to a variety of surfaces. So, what are the advantages of using hot melt adhesive in this regard? 01 Environmental Protection Currently, the hot melt adhesives used in labels, which are common in our daily lives, have a solid...
Removable labels feature low peel force and can be removed cleanly from the surface after a period of time without contamination. These require a low-tack adhesive that can be removed without residue after rigorous aging. Currently, a widely adopted low-cost removable adhesive design involves adding a small amount of crosslinking agent to a general-purpose low-tack pressure-sensitive adhesive to i...
Packaging and Printing Scenarios 1. Acrylic emulsion for paper packaging bonding: Strong adhesion, environmentally friendly and odorless. 2. Acrylic emulsion for color box printing: Good adhesion, vibrant colors that don't peel off. 3. Acrylic emulsion for corrugated paper bonding: Strong water resistance, cardboard boxes are resistant to pressure and don't easily fall apa...
The following are examples of acrylic emulsion applications in textiles and special applications, along with their demonstrated characteristics and features: 1. Fabric Coating with Acrylic Emulsion: Imparts waterproof properties while maintaining breathability. 2. Nonwoven Fabric Bonding with Acrylic Emulsion: Provides strong adhesion and enhances the strength of nonwoven fabri...
Acrylic adhesives are renowned for their excellent overall performance, especially in industrial applications requiring high strength, aging resistance, and rapid curing. Key Features High Strength and Toughness: After curing, they form a strong and tough adhesive layer, with particularly excellent impact and peel resistance. Rapid Curing: Second-generation acrylates (SGA) and UV-cu...
The Secret to Non-Peeling Labels: How Adhesives Determine Label Lifespan In everyday packaging, label peeling is a common yet troublesome problem – not only affecting product appearance but also potentially raising consumer doubts about quality. But have you ever considered that a crucial science lies behind this: adhesives? Adhesives: The "Invisible Guardians" of Labels Adhesives a...
Seeking a packaging seal that balances both strength and eco-friendliness? Water-based acrylics offer the perfect "best-of-both-worlds" solution! As a core raw material for sealing adhesives, they are widely utilized across diverse packaging applications—including food, express delivery, and daily chemical products. Whether applied to paper boxes, plastic bags, or composite film materials, they en...
As environmental regulations tighten globally and end users increasingly prioritize health and sustainability, the adhesive industry is undergoing a fundamental shift from solvent‑based to eco‑friendly alternatives. Among the various solutions, waterborne acrylic emulsion has emerged as a leading material due to its excellent balance of performance, versatility, and environmental compatibility. Wa...
If you are a manufacturer of—or a user of—hot-melt adhesives, you are well aware that while most hot-melt pressure-sensitive adhesives (HMPSAs) appear virtually identical in appearance, the specific manufacturing processes employed during their blending result in distinct sets of advantages and disadvantages. Hot-melt pressure-sensitive adhesives are complex mixtures composed of SBC (Styrene-Butad...
1. Hot Melt Adhesives – Coating Methods Hot melt adhesives are 100% solids, require heating to melt, and solidify upon cooling. They are solvent‑free and cure quickly, making them ideal for high‑speed production. Roll Coating How it works: Molten adhesive is transferred to the substrate via a heated gravure or applicator roll. Coating thickness is controlled by the roll’s surface pattern. Applicat...
