Packaging tape is essential to ensuring the safety of both the contents inside and the boxes they are sent in. Failed seals and other expensive inefficiencies like rework and line stoppage might be caused by the improper tape or application method. To ensure that boxes are properly sealed, commodities are safe, and lines operate smoothly, start with the correct tape.
However, certain applications or operations need customised packaging solutions that are tailored to their unique needs. The usage of recyclable corrugated boxes and cold packing settings are two instances of this.
When it comes to using tape, Recycled Packaging might be rough.
Recycling corrugated cardboard is a major factor in the rise in the usage of this material. The shipping industry has transitioned to processing and delivering an ever-increasing amount of corrugated packages as corporations become more ecologically conscious. As a consequence of the worldwide epidemic, eCommerce has seen a considerable increase. The need to send larger, bulkier and more expensive items, such as food, drinks, industrial equipment, and electronics, has increased as a result of this trend. This has been happening for some time, but the pandemic's increased demand has increased the need for recycled corrugated cardboard even more.
100% virgin fibres, 100% recycled fibres, or a mix of the two may be used to make these crates. Environmentally-friendly packaging has led to an increase in both recycled cardboard boxes and recycled fibre content in corrugated cardboard boxes, with many packaging businesses now utilising 100% recycled content in corrugated cartons.
The adhesives used to seal the cartons have to be modified because of the changes in carton structure. On fresh corrugated boxes, getting a firm seal is significantly simpler. Longer and more porous fibres enable a deep and quick-forming connection with the adhesive of the packing tape. The substrate undergoes a substantial transformation throughout the recycling process. Shorter fibres are packed closer together because the paper is cut up and repulped, resulting in shorter fibres. With six recycling cycles per corrugated box fibre, it is possible to create cartons with very short fibres by going through this process repeatedly. A less porous surface results, making it more difficult for the tape's adhesive to enter and adhere to it.
Due to a rise in the need for shipping, hot melt packaging tape producers have created adhesive formulations especially for sealing highly recycled corrugated cardboard boxes, such as 100% recycled cartons. This kind of hot-melt packaging tape is designed to reduce the risk of compromised shipments and open returns for manufacturers and distributors by providing sturdy, secure box sealing tape solutions.
The Wrong Adhesive Can Be Frozen in Cold Environments.
Recycled packaging has a rough surface, but other businesses have to cope with the issues of cold packaging as well. Temperatures below 35F may make it difficult for packing tape to hold, whether in cold climes or unheated warehouses and storage facilities, for frozen goods, meat and poultry processing and dairy facilities, which must all stay refrigerated for health and safety reasons.
Tape's viscoelasticity, the mix of liquid and solid qualities, makes it difficult to adhere to freezing temperatures. The tape's tackiness decreases when the liquid component solidifies. The tape won't stick to the packing if it can't get in touch with the surface. The adhesive must be able to make a durable bond to the package without freezing in cold settings to prevent tape failure.
It is not suggested for automated applications, despite its broad temperature range, to use acrylic tape. The lack of a release layer on acrylic ZA tapes makes unwinding them more difficult and necessitates using greater effort. This increases the tension on the tape's film backing during the automated application, resulting in early breakouts, downtime, and tape waste.
For automated palletization, the acrylic tape does not have the shear strength or holding power. Machine-grade hot melt tape with correct unwind qualities and a synthetic rubber/resin adhesive that forms a fast, permanent connection in subfreezing conditions is the finest solution for a cold-environment automated packaging line.
A robust tape is required for truly difficult applications. The quality tape will keep items safe and secure, especially in demanding packaging and temperature environments.
