From simple wrapping of freshly baked products to high speed frozen pizzas, there is a common theme to handle delicate products while eliminating contamination. As a result, it’s important you choose the best method to shrink wrap bakery products to achieve the best seal.
Side seal is best to shrink wrap bakery products
When comparing side seals with lap seals, the side seal shrink wrapper excels as they are most reliable in the environment while considering all the necessary food standards. Crumbs, toppings, and other debris inherent in the bakery environment do not compromise the integrity of a side seal as they can using a lap seal wrapper. A consistently secure lap seal is harder to make than a positive side seal and lap seal defects (open seals) are harder to spot. Side sealers often use less film because lap seal plows often have to be oversized due to the variation in size and shape of baked products.

How Side Seal Shrink Wrappers are Bakery Friendly
1. Simple Setup
A consistently positive, secure lap seal is much harder to make than a positive side seal.
2. Less Contamination
Lap seals are prone to open seals due to crumbs and other debris inherent in the bakery environment. Since side sealers do not seal on the bottom of the package, they are impervious to seal contamination from debris.
3. Spot Imperfections Faster
Lap seal defects (open seals) are harder to spot.
4. Use Less Shrink Film
Side seal wrappers potentially use less film. On bakery applications, lap seal plows frequently have to be oversized to account for variations in product size or shape thus using more film.
5. Use Multiple Film Sizes
Lap sealers need precise film sizes meaning you must carry a variety of sizes in inventory. Side sealers are flexible with film and can accommodate different size or shape packages.
6. Quick Product Changeovers
Side seal wrappers don’t need parts to accommodate for different product sizes.
7. Fewer Changeover Parts
For lap seal shrink wrappers, each product must have it’s own plow as a change parts. Side sealers an adjustable unit for different size or shape products.
