Reseal Label — Wet Wipes
The Challenge
A prospective customer was in search of solutions to problems with a current functional part of their packaging. The product is a high-profile, non-woven wipe in a soft-pack film package. The wipes are sealed inside of a form-fill-seal film with a lap-seal and a pre-die-cut opening. The opening on the package has a multi-use functional resealable label affixed over it to allow easy access to the individual wipes within and the protective resealable label on the outside top center of the package for multiple uses.
Before
- A physical discoloration to the resealable label. The discoloration showed up as a dark oval ring around the opening area and was easily visible and not aesthetically pleasing.
Before
- The label material that was being used was a white polyolefin film that would easily split and tear in the direction of the label pull to open, which was also not desirable as it rendered the label useless as a resealable functional closure.
The Solution
Within a week, LUX R&D had not only identified the cause of the discoloration — a negative chemical reaction between the salicylic acid contents of the product and the adhesive and film type being used — but also determined the correct base label material to ensure proper functionality and prevent splitting and tearing.
LUX R&D did some research internally and with various film and adhesive suppliers to help determine which adhesive and label material combinations offered the best product resistance to salicylic acid and function without impacting the rest of the packaging or the functional needs of the label. Once some options were determined, control labels (current) and sample material combinations were applied to the product and tested. Testing for discoloration, adhesion and resealing, exposure/time, and function (opening and closing) was conducted, and the results were reviewed.

The Result
Ultimately selecting, testing, and using the correct base-film and proper adhesive that worked well with the product chemistry provided an excellent solution. LUX was successful with eliminating the unsightly discoloration and the physical tearing failure of the label. This was accomplished without impacting the needed functionality of the label on the package. Both corrections allowed for a competitively priced resealable product label.
Sample labels were provided to the customer for line trials, exposure/time, and opening/closing testing with excellent results. The labels not only functioned as needed but also provided a reliable solution to a cosmetic and functional problem to a well-known brand. LUX’s approach to finding this solution helped to bring in new business with a customer that saw firsthand the genuine interest in helping their brand.
The goal was clear: find a solution that solved an ongoing current supplier problem, and with the LUX R&D team’s innovative problem-solving skills and humble approach, the right solution was quickly found and provided to the customer.
