Matrix Removal and Exposed Adhesives
A couple of weeks ago we discussed the advantages to pneumatically conveying label matrix with exposed adhesives. Keep in mind, there are two methods for handling matrix with exposed adhesive.
You may elect to use an oil injection system or powder to neutralize the adhesive, so that it will not stick to duct and other components in the pneumatic conveying system. This method is effective; however, keep in mind that it can be messy (especially over time) and attention to the delivery system is necessary to make sure the neutralizing agent is consistently applied to the adhesive (the oil reservoir for example). The adhesive neutralizing agent, either oil or powder, will be discharged along with the matrix into whatever collection method is used. Some consideration on how to handle this airborne contaminant may be necessary.
Teflon or plasma coating can be used on all the exposed areas within the trim removal system to assure the adhesive will not stick to components. This method is very effective for handling waste with exposed adhesive and is clean and maintenance free. However, initial cost can be high.
