  1. Lap Seal/Side Seal Comparison

  2. Lap Seal • Potentially uses less film • On bakery applications, plow frequently has to be oversized to account for product size or shape variation thus using more film • A positive lap seal is harder to make than a positive side seal • Lap seals are prone to open seals due to crumbs and debris inherent in the bakery environment • Lap seal defects (open seals) are harder to spot • Not all films will work on a lap seal machine • Precise film sizing is critical which means more film sizes in inventory • Changeover between products takes longer • Each SKU requires the investment in a plow

  3. Side Seal • Works with a wider variety of films • More flexible when product size or shape varies- simple adjustment vs plow size change • Easier to monitor seal quality • Easy to visually tell good from bad seal • Can catch bad packages before they go in the case to the customer • Fewer returns or complaints • Impervious to seal contamination from product debris • Fast changeover between products • No parts required for changeover • Fewer film sizes required- lap seals require exact sizes • Uses slightly more film for selvage trim • Seal is on side of package vs the face • Some customers prefer hiding the seal on the package edge vs having it on the face • Graphics or instructions on package back are more easily visible

  4. Advantagesof Texwrap Lap Seal • Doboy machines are designed for hard films vs shrink film • Texwrap machines have the ability to relax the film between packages to create more positive end seals • Package cut-off length can be less because our patented servo orbital sealing jaws close vertically • Texwrap lap sealers can be fitted with a variety of lap seal options • Thermal/drag wire • Heated drag block • Air jet • Static • Coated band seal • Some styles can be combined • Easy access to plow for threading • Quick change plows • Texwrap plows are less expensive • Can use double- put up rolls of film because of cradle design vs Doboy spindle design • Parts available in 1 day • USA made • 3-year Built-Better/Backed-Better warranty • Local service available through Texwrap distributors nationwide
