Double-sided tape, full name double-sided tape, is a kind of tape coated with high performance pressure-sensitive adhesive on both surfaces of the substrate (such as non-woven cloth, film, foam, etc.).
Core Structure: usually consists of three parts
Release Paper/Film: protects the adhesive surface and is removed during use. Common types include single-sided and double-sided release.
Base Material: the skeleton of the tape determines the thickness, flexibility, tensile strength and other basic physical properties of the tape.
Adhesive: The core function is to bond. The viscosity, temperature resistance, and weather resistance vary depending on the composition.
How it Works: With a slight press, the adhesive creates an adhesive force with the surface of the object to be glued, thus firmly bonding the two objects together.
Main Features: easy to use, fast bonding, no need to wait for curing like liquid glue, clean and stain free, stress distribution is uniform.
Our products mainly fall into these categories: Oil-based Double Sided Tape, Hot Melt Double Sided Tape, Embroidery Double Sided Tape, etc.
There are many kinds of double-sided tape, according to the different substrate and adhesive, can be divided into the following categories:
Base Material: non-woven material.
Features: moderate thickness, good flexibility, smooth adhesion, not easy to deform. It is the most common and universal type.
Common Applications: stationery and office supplies, home decoration (such as hooks, photo walls), gift packaging, car interior, trademark adhesion, etc.
Representative: Most of the most common "double-sided tape" on the market belong to this category.
Substrate: use kraft paper or cotton paper.
Features: easy to tear, easy to process, cheap, but poor temperature resistance and waterproof.
Common application: mainly used on the back of masking tape for shielding and protection during spraying and baking.
Substrate: polyester film.
Features: thin material, high strength, good temperature resistance, high transparency, chemical corrosion resistance.
Common applications: electronic products (such as mobile phone, tablet screen, battery, housing fixation), nameplate, film switch, glass bonding, etc.
Base Material: acrylic or polyethylene foam.
Features: excellent buffering, sealing and filling performance, can fit irregular surfaces, strong adhesion.
Common Applications: construction industry (such as aluminum plate, stone, metal curtain wall bonding and sealing), automobile (such as trim strip, rain shield, license plate), home appliances (such as accessories installation), sound insulation and shock absorption.
3M VHB (Very High Bonding Strength) tape is a prime example of foam tape.
This is classified by adhesive type:
Acrylic Adhesive: Excellent comprehensive performance, weather resistance (high temperature, low temperature, aging resistance), excellent solvent resistance, long-term use is not easy to turn yellow. It is the mainstream of high-performance double-sided adhesive.
Rubber Adhesive: high initial adhesion, fast bonding speed, but sensitive to temperature and solvent, may age and remove rubber for a long time, relatively cheap price. Mostly used in some daily applications that do not require high durability.
Choosing the right double-sided tape is key to successful bonding. You can follow these steps to consider:
Surface Energy: This is one of the most important factors.
High Surface Energy Materials (such as metal, glass, ceramic, ABS plastic): easy to bond, most double-sided tape is suitable.
Low Surface Energy Materials (e.g., polyethylene PE, polypropylene PP, silicone, Teflon) are extremely difficult to bond and require specialized adhesives such as modified acrylic adhesives.
Surface Roughness: Rough or porous surfaces (such as cement walls, wood) require thicker, more filling tape, such as foam tape.
Temperature: Will the adhesive be exposed to high or low temperatures after bonding? The temperature range of the adhesive must be selected to cover the temperature of the environment in which it is used.
Humidity/Water/Chemicals: Is waterproofing or solvent resistance required? Outdoor use requires excellent UV and aging resistance. Acrylic glue is generally superior to rubber glue in this regard.
Indoor or Outdoor: Outdoor applications require high weather resistance.
Adhesive method:
Permanent Bonding: requires high-strength, durable tape, such as VHB foam tape.
Temporary Adhesive: Use tape with moderate initial tack that removes without residue, such as some double-sided adhesive for non-woven fabric.
Force type:
Shear Force: the force of two objects sliding parallel to each other (such as a hook on a wall). Foam tape is very resistant to shear force.
Peeling Force: the force to tear from the edge (such as tearing a delivery box). The tape needs to have good toughness and initial adhesion.
Load-Bearing: How heavy is the object to be bonded? The heavier the weight, the larger the bonding area required, or the stronger the adhesive tape needs to be selected.
Thickness and Filling Gap: Need to fill the gap between two surfaces? Foam tape is the ideal choice.
Appearance: Do you want it to be transparent, white, or black? The visibility of the tape will affect the appearance.
Ease of Use: Does it require manual tearing? Does it need strong initial adhesion for quick positioning?
Select the Base Material: What should you stick to? (Plastic, metal, glass, wallpaper?)
Specify the Environment: indoor, outdoor, high temperature, or humid?
Analyze the Force: How much force is required? Is it permanent bonding?
Comprehensive Selection: Based on the above three points, select the base material type (foam, non-woven fabric, PET) and adhesive type (acrylic, rubber).
One Final Tip: If you're not sure, the best way is to test it on a small area or unimportant area, or consult us, who can give you professional advice.
Kraft Paper Tape, as the name suggests, is a kind of tape made of glossy paper as the base material and coated with pressure-sensitive adhesive. It combines the excellent characteristics of traditional kraft paper with modern adhesive technology.
High Strength: Kraft paper substrate itself has long fiber and good toughness, so that it has strong resistance to tearing and tensile strength.
Environmentally Friendly and Recyclable: The main raw material is wood pulp fiber, which can be naturally degraded and recycled, in line with modern environmental concepts. Many varieties also use water-based acrylic glue or hot melt glue, which is more environmentally friendly.
Aesthetic Simplicity: The appearance is a natural yellowish brown of kraft paper, giving people a retro, solid and simple feeling, often used to enhance the taste of packaging.
Easy to Tear: Most kraft paper tape can be torn open with your hands without tools, which is convenient to use.
Excellent Printability: The surface is suitable for printing and can be customized with a company logo or brand identity, making it ideal for brand packaging.
Kraft Paper Tape can be classified according to substrate, adhesive, function and appearance：
Pure Wood Pulp Kraft Paper Tape: The most common type, low cost, wide application.
Washi Tape (also known as masking tape): Made from Japanese-imported washi paper, a fiber derived from the bark of the paper mulberry tree, it is finer and softer than regular kraft paper, with excellent flexibility and no residue after peeling. It is widely used for crafts, decoration, and covering.
Reinforced Kraft Paper Tape: Glass fiber or plastic fiber is inserted into the kraft paper to greatly enhance the longitudinal tensile strength of the tape, which is specially used for the sealing and reinforcement of heavy paper boxes.
Hot-Melt Kraft Paper Tape: The adhesive layer is coated after solid adhesive is heated and melted. It has good initial adhesion and fast adhesion, but the high temperature resistance is slightly poor, and it may age and become brittle in the long run.
Water-Based Acrylic Adhesive Kraft Paper Tape: The adhesive layer is water-based acrylic adhesive. The initial adhesion is slightly slow, but the bonding force will be very strong after a period of time, excellent high temperature and aging resistance, more environmentally friendly and odorless.
Rubber-Based Kraft Paper Tape: Strong adhesion, good low temperature resistance, but may have some odor.
Light Packaging for Daily Household and E-Commerce: Choose ordinary water-free hot melt adhesive kraft paper tape, which is cost-effective and easy to use.
Heavy-Duty Carton/Logistics Transportation: Always use reinforced kraft paper tape, which is far safer than ordinary tape.
DIY/Gift Decoration: Washi Tape is the top choice, offering a wide range of colors and patterns with easy application.
Focus on Environmental Protection: Prioritize products labeled as "Water-Based Acrylic Glue".
Test: If you are not sure, you can first buy a small batch to try, and test its bonding effect on different material surfaces (such as rough carton, smooth surface).
Warning Tape, also known as caution tape, is a strip of material with eye-catching words (such as "No Pass", "Dangerous Area", "Caution Electric Shock") and/or patterns (such as stripes, slashes, skull) printed on the surface.
Its core function is not physical binding or fixation, but visual warning and area division. Through its bright colors and clear text, it can quickly attract people's attention, convey specific warning information, so as to prevent accidents, protect the safety of personnel, isolate danger or temporarily control the area.
Visibility: Use color combinations with high contrast (such as yellow and black, red and white) that are easy to recognize even in poor light.
Warning: Printed with a clear warning, directly informing the type of danger or prohibited behavior.
Temporary: Most warning tapes are easy to stick and remove, and are often used in temporary construction sites, accident sites or maintenance areas.
Low Cost: As an efficient and low-cost security management tool, it is widely used.
Warning Tape can be classified by color pattern and application scenario.
By Color and Pattern (Most Common Classification Method)
This is the most intuitive classification method, different color combinations usually represent different types of warning, has formed an international convention.
Yellow and Black Warning Tape (Tiger Pattern):
Meaning: Mainly means "Pay Attention to Safety, Beware of Tripping and Collision". It is used to remind people to pay attention to obstacles, ground elevation difference or general dangerous areas ahead.Application: Construction site, around machinery and equipment, temporary storage, ground hole.
Sign Meaning: "No Entry, Hazardous Area". It has the strongest warning effect and is usually used to isolate fire risk areas, electrical hazard areas, accident core sites, etc.Application: Around fire fighting equipment, in front of distribution box, accident warning line, high voltage danger zone.
Meaning: Indicates "Safe Zone, Pass Sign". Used to mark the location of safety facilities, first aid points, evacuation routes, or safe isolation areas.Application: Emergency station, safety passage, emergency assembly point.
Meaning: Indicates "Indication or Reminder" with less enforcement. Used to mark information or items requiring special attention, such as "Under Repair" or "Inspection Area".Application: Equipment inspection area, temporary warehouse entrance.
Yellow and White Warning Tape:
Meaning: Similar to yellow and black, it indicates "Pay Attention, Walk Slowly", but the warning level is slightly lower. It is often used for indoor crowd control, queue areas or passages that need careful passage.Application: Crowd control in shopping malls and exhibitions, and clean room passages.
The following key factors need to be considered when choosing the right warning tape：
High-risk area: Red and white warning tape is recommended.
Safety/Obstacle Warning: Use yellow and black warning tape first.
Indicate safe area/evacuation route: Select green and white warning tape.
Adhesion: Ensure the tape adheres firmly to the surface (e.g., floor, wall, column) and does not easily peel off.
Strength and Durability: Select materials with strong tensile and tear resistance according to the duration of use and possible foot and vehicle trampling.
Size: Note the width (commonly 4.5cm, 4.8cm, 7.2cm) and length of the tape. The wider the tape, the more noticeable it will be.
Fiber Tape, commonly known as "Reinforced Tape", is a type of tape that incorporates high-strength polyester fibers into its PET composition.
Plastic Substrate: Provides waterproof, moisture-proof and backing functions.
Built-in Fiber: Like the steel bars in reinforced concrete, it provides the tape with high tensile strength and tear resistance.
Grid Fiber Tape: The warp and weft fibers are interwoven into a grid pattern. This structure gives the tape high strength in both length and width, effectively preventing carton seams from bursting under pressure, and providing better anti-explosion box effect.
Striped Fiber Tape: The fibers are embedded in parallel straight lines. It provides high tensile strength along the length of the tape, and is relatively easy to tear laterally, making it easy to handle by hand.
Use Grid Fiber Tape in the Following Situations
The contents of the package are very heavy or valuable.
The volume of carton is large, which requires high stacking, and the overall strength of the box is required to be high.
It is necessary to ensure that the carton does not crack in any direction during transportation.
Use Striped Fiber Tape in the Following Cases
It meets the daily demand of most heavy cartons.
The pursuit of convenience requires frequent tearing of tape by hand.
Packaging and transportation conditions are relatively conventional and do not require extreme explosion protection.
According to the distribution of fibers, fiber tapes can be divided into the following two types：
Glass fiber or polyester fiber is formed into a dense grid structure by interweaving warp and weft, and completely covers the tape substrate.
Isotropic Strength: Because the fibers are in a grid, the tensile strength and tear resistance in both length and width are basically the same.
Explosion-Proof Function: This structure can effectively disperse the stress from different directions, and can prevent the box from bursting at the joint to the maximum extent when the carton is compressed or impacted.
Suitable for scenarios requiring high strength and all-round protection, such as heavy equipment packaging, carton sealing for long-distance transportation or high-altitude stacking.
Reinforced fibers (usually glass fibers) are embedded in the tape substrate in the form of parallel, spaced straight lines, and appear in a striped appearance.
Longitudinal Strength: The fibers provide extremely high tensile strength along the length of the tape, making it very difficult to break in the longitudinal direction.
Transverse Tear Resistance: Due to the gap between the fiber stripes, the tape is relatively easy to tear in the transverse direction, which is easy to tear by hand.
Suitable for most conventional occasions that need high strength packaging but do not need all-round explosion-proof, is the most commonly used model in daily heavy packaging.
