Print and publishing shrink wrapping
Book shrink wrapping machine
Books, manuals, catalogues and printed packs need careful shrink wrapping because the finish has to look clean without damaging corners or distorting the product. L sealers are often used for this work because a regular rectangular product can be sealed efficiently before travelling through the heat tunnel.
Machine choice for print products
- Manual or semi automatic L sealer for mixed short-run print work.
- Automatic L sealer for repeat sizes and higher daily volumes.
- Tunnel airflow and temperature controlled to avoid excessive heat on paper products.
- Film width chosen to reduce waste while leaving enough overlap for a secure seal.
Key risks to avoid
Books can show poor results if the tunnel temperature is too high, the film is too tight before shrinking, or the pack enters the tunnel with loose film folded under the edge. A good specification review should look at the book thickness range and the largest product size.
Information needed before quoting
Send the largest and smallest book size, typical stack thickness, daily output, whether packs are single or bundled, and whether the finished pack needs retail presentation or transit protection.
Specification summary
For a reliable recommendation, send product dimensions, photographs, required output, film preference, available floor space, power and compressed air details. Lancing UK can then check the correct machine aperture, heat tunnel size, conveyor layout and operator access before quoting.
FAQ
Book shrink wrapping machine FAQs
Can an L sealer shrink wrap books?
Yes. Books and printed packs are common L-sealer applications because the product shape is regular and easy to seal.
Will shrink wrapping damage books?
Correct film choice and heat-tunnel settings help protect the product. Overheating or poor product spacing can cause distortion, so specification matters.
Can one machine wrap different book sizes?
A machine can often handle a range of sizes, but the maximum length, width, height and film width need to be checked.
