Carton Sealing Tapes

General Information: Carton sealing tapes are generally used for packing and sealing boxes. Corrugated cardboard boxes sealed with the proper carton sealing tape maintain their integrity and hold their contents securely. Since carton sealing tapes are used for sealing boxes, the adhesive system, backing strength and other physical properties must perform to the required task. Consequently, there are many grades and varieties of carton sealing tape. Recycled corrugated cardboard may require an altogether different carton sealing tape than cardboard that is not recycled.

Technical Details: Carton sealing tapes have three principal adhesive systems: natural rubber, hot melt and acrylic adhesive. The backing is typically clear (sometimes the customer prefers tan) biaxially oriented polypropylene (“BOPP”) film, but some paper tapes are used for carton sealing.

• Higher end kraft flatback paper tapes have a silicone release coating on the back of the paper while the adhesive system is typically synthetic rubber based. Lower end water activated paper tapes are slowly being phased out as they are messy and difficult to apply. Paper tapes offer flexibility for sealing carton corners, edges and irregular surfaces, and they are environmentally safe since they may be biodegradable and recyclable.
• Hot melt adhesive systems have better quick stick bonding to corrugated paperboard while acrylic adhesive systems require more time to set up and form a bond, but acrylic adhesives have better long lasting adhesive properties.
• Carton sealing tapes may be applied by hand with hand held dispensers, or they may be machine applied. In acilities that use significant amounts of carton sealing tape, it may be desirable to use a carton sealing tape with a quiet unwind so as to reduce noise. Both paper and BOPP carton sealing tapes may be printed and customized with a logo, corporate information or specific color. Also, certain carton sealing tapes are tamper evident and will signal when a package has been opened or tampered with.
• Carton sealing tapes are available in different widths and lengths, and heavy duty carton sealing tapes, general purpose, or economy grade products are held in stock because of the high volume and broad application for these products. In addition to different strengths and thicknesses, the shear properties of carton sealing tapes may also vary.
