Using a shrink sleeve, a product is wrapped around the entire perimeter, fitting perfectly around the container. With a shrink-sleeving machine, you can apply labels to various sizes, shapes, and designs of various containers. With a Sleever machine, endless labeling possibilities exist, as the design can be centered around the container.
- A full-body sleeve covers the entire product and provides excellent shelf appeal and marketing advantages.
- These Sleever form a tight seal over the closure of a product to keep it safe and are usually seen on supplements, cleaning products, and beverages.
- The multipack sleeve is used for multiple packaging products in one special package and bar code. It is commonly found in cleaning products and beverages.
- An example of standard sleeves is juice or bottled water, which do not have tamper-evident seals but cover most of the product.
The sleeving process is generally straightforward, regardless of the sleeving machine you select:
- Your shrink wrap film must be loaded into the machine before you wrap the product.
- When your packaging goes through the machine, the shrink sleeves are dropped loosely on top of whatever you need to wrap.
- After passing through a shrink tunnel, the sleeve or film is shrunk to fit seamlessly around the product due to heating or steam application. Although steam can achieve a better result, it is more expensive, so heat is the preferred method in standard production.
Depending on the product and the machine’s capabilities, this process can be performed either pre- or post-formulation, with sleeves made from PVC, PET, or OPS. Generally, the better a sleeving machine is, the more it will cost. However, as with any machine, the more features it has, the faster it will work and the simpler it will be to integrate with existing production lines. When cleaning your sleeving machine, follow the manufacturer’s instructions because every machine is different. You’ll have to follow your industry and any regulations or guidelines you need to follow, along with the machine’s components and the solvents you use.
