Core starting tape is a specialized type of adhesive tape used in the printing industry to secure the core of a roll of paper or film to the winding shaft. It is essential for ensuring that materials like paper, plastic films, or metal foils start winding around a core (a cylindrical tube upon which these materials are wound for storage and handling) smoothly and securely. It plays a crucial role in preventing the core from slipping or shifting during the printing process, ensuring smooth and efficient operation.
Core starting tape adhere to a variety of coated and uncoated paper grades. Core starting repulpable tapes dissolves in water, is biodegradable and can be recycled. Super thin core tapes are PET film double side tape. It secure the film rolls was no bulge at the adhesive tape adhered.
Features
Core starting tape typically features a strong adhesive on one or both sides, depending on its specific application. The tape is designed to adhere well to both the core and the material being wound, providing a reliable initial bond that won't easily come undone as the material is rolled. Here are some key characteristics:
Adhesive Strength: The tape has a high-tack adhesive that ensures a strong bond with the core and the first layer of the material to prevent slipping or detachment during the winding process.
Durability: It is durable enough to withstand the tension and pulling forces that occur during the winding process without tearing or stretching.
Temperature Resistance: It can withstand the high temperatures generated during the printing process.
Chemical Resistance: Resistant to various chemicals and solvents used in the printing industry.
Width and Thickness: The width and thickness of the tape are chosen based on the type of material being wound and the size of the core. It needs to be strong enough to hold the material but not so thick as to create unevenness in the initial layers of the rolled product.
Applications
Paper Manufacturing: In the production of paper rolls, core starting tape is used to secure the end of the paper sheet to the core, ensuring a smooth start to the winding process.
Film and Foil Manufacturing: For materials like plastic films and aluminum foils, the tape helps in starting the roll process without causing damage or deformation to the delicate films or foils.
Textile Industry: Core starting tape is also used in textile manufacturing for winding fabrics and other fibrous materials.
Benefits
Efficiency: Using core starting tape speeds up the process of changing rolls and reduces downtime in manufacturing settings.
Quality Control: It helps maintain the quality of the roll by preventing slippage and misalignment at the start of the roll, which could lead to defects in the wound product.
Versatility: Different types of core starting tapes are available to suit various materials and core sizes, making it a versatile solution in many roll-to-roll manufacturing processes.
Installation Tips
When applying core starting tape, it is important to ensure that the surface of the core and the material are clean and free from dust or oil, which could impair adhesion. The tape should be applied evenly and smoothly to avoid wrinkles or air bubbles that could interfere with the winding process.
In summary, core starting tape is a crucial component in the efficient and effective production of rolled materials across various industries, aiding in the seamless initiation of new rolls on cores. Its strong adhesive properties and durability make it an indispensable tool for maintaining high standards of production and quality.
