How does gummed tape work?
As a trusted gummed tape supplier, I've witnessed firsthand the widespread use and effectiveness of this remarkable product across various industries. Gummed tape, also known as water - activated tape, is a staple in packaging and shipping operations. In this blog, I'll delve into the science behind how gummed tape works, explore its benefits, and showcase some of our high - quality offerings.
The Composition of Gummed Tape
Gummed tape typically consists of three main components: a backing material, an adhesive layer, and sometimes a reinforcing element.
The backing material is often made of kraft paper. Kraft paper is known for its strength, durability, and eco - friendliness. It can withstand the rigors of handling, shipping, and storage. The paper's fibrous structure provides a solid foundation for the tape, allowing it to conform to different surfaces and shapes.
The adhesive layer is the key to the tape's functionality. It is usually a starch - based adhesive. Starch is a natural polymer derived from plants such as corn, wheat, or potato. When dry, the adhesive is hard and inactive. However, when it comes into contact with water, a chemical reaction occurs. The water molecules break down the starch chains, turning the adhesive into a sticky, gooey substance.
Some gummed tapes are reinforced with fiberglass or other materials. Reinforcement adds extra strength to the tape, making it suitable for heavy - duty applications. For example, our Reinforce Water Activated Tape is designed to handle large and heavy packages, providing reliable sealing even under high stress.
The Activation Process
The activation of gummed tape is a simple yet crucial step. To use gummed tape, you first need to wet the adhesive side. This can be done using a water dispenser specifically designed for gummed tape. The dispenser has a brush or a roller that applies water evenly to the adhesive.
Once the adhesive is wet, it becomes tacky within seconds. You can then place the tape on the surface you want to seal. As the water evaporates, the starch adhesive re - solidifies, creating a strong bond with the surface. This bond is not just a simple physical attachment; it is a chemical bond that is difficult to break. The adhesive seeps into the pores of the paper or other materials, creating a tight seal that can withstand vibrations, impacts, and changes in temperature and humidity.
The Bonding Mechanism
The bonding of gummed tape is based on several physical and chemical principles.
On a physical level, the adhesive fills the microscopic irregularities on the surface of the materials being joined. This interlocking effect provides mechanical strength to the bond. For example, when sealing a cardboard box, the adhesive seeps into the rough surface of the cardboard, creating a secure connection.
Chemically, the starch adhesive forms hydrogen bonds with the molecules on the surface. Hydrogen bonds are relatively strong intermolecular forces that hold the tape and the surface together. The re - solidification of the starch also contributes to the bond strength. As the starch dries, it forms a rigid matrix that locks the tape in place.
Advantages of Gummed Tape
One of the main advantages of gummed tape is its security. Unlike pressure - sensitive tapes, which can be easily peeled off, gummed tape forms a permanent seal. Once applied and dried, it is extremely difficult to remove without damaging the package. This makes it an ideal choice for securing valuable or sensitive items during shipping.
Gummed tape is also environmentally friendly. The kraft paper backing is biodegradable, and the starch - based adhesive is non - toxic. As more and more companies are looking for sustainable packaging solutions, gummed tape fits the bill perfectly.
In terms of cost - effectiveness, gummed tape offers long - term savings. Although the initial investment in a water dispenser may be required, the cost per roll of gummed tape is often lower than that of other types of tapes. Additionally, its strong bond reduces the risk of package damage during transit, which can save on replacement and return costs.
Applications of Gummed Tape
Gummed tape is used in a wide range of industries. In the e - commerce industry, it is used to seal shipping boxes. With the increasing volume of online shopping, the demand for reliable and secure packaging solutions is higher than ever. Our White Reinforced Water Activated Tape is a popular choice for e - commerce companies as it provides a clean and professional look.
In the food industry, gummed tape is used to seal food packaging. The natural starch adhesive is safe for contact with food, and the tape's strong seal helps to keep food fresh and protected.
The manufacturing industry also relies on gummed tape for product packaging. Whether it's small components or large machinery parts, gummed tape can provide a secure and durable seal.
