In the flexible packaging industry, splicing performance plays a vital role in maintaining efficient through-put for converting processes under varying speeds and process conditions.
While a number of adhesive choices are available for core starts and splicing applications, such as spiraled masking tapes or liquid glue, the use of pressure-sensitive adhesive (PSA) splicing tapes offer flexible packaging manufacturers and converters a number of benefits. PSAs deliver consistent, immediate bonds with minimal preparation, no adhesive dry times and eliminate liquid splash to finished product, all of which improve both down time and clean-up time. A PSA splicing tape used in place of a liquid adhesive allows for uniform thickness of the adhesive during application without the need for application equipment, specialized storage or the use of solvents.
There are a number of factors to consider for ensuring that the proper adhesive is selected for the application. For this reason, flexible packaging manufacturers and converters will benefit most by working directly with a qualified adhesive consultant who can thoroughly evaluate the manufacturing or converting process and the substrates to be spliced. Additionally, manufacturers and converters can eliminate the guesswork in selecting the right product(s) to trial, based on performance data and studies conducted in reputable research and development laboratories.
Three key conditions to consider when selecting the proper product for a particular processing line are heat, shear and adhesion/bond to the specific substrates to be spliced. Also, as manufacturers and converters are pressured to perform with higher through-put, line speed has become an important factor in selecting the right adhesive for optimal performance. A splicing tape expert can offer important insight on which adhesive formulations and coat-weights are best suited for particular substrate classes based on the line speed and process conditions.
As mentioned previously, working closely with an adhesive or splicing tape specialist who understands the process of a particular equipment line to specify the appropriate product for the application is the best way to identify problems and offer a solution so the right products are on-hand to ensure optimal process performance. In most situations, a splicing challenge can be addressed by our full line of splicing tape products. However, Adhesives Research does utilize extensive in-house R&D capabilities to modify existing adhesive technologies to address unique application requirements in the industry.
