Description

Bake, Pack, Repeat!

Keep your baked goods looking their best with Mantle Packaging’s reliable and easy-to-use L Sealer Range!

Mantle Packaging Machinery Ltd manufactures a fantastic lineup of food packaging machines, including a specially designed range of L Sealers perfect for your bakery. These machines are made to work seamlessly with centre-folded polypropylene films, ensuring your baked goods are wrapped efficiently and professionally.

Meet the LS30, our mid-sized superstar in the L Sealer family!

Equipped with an impulse sealing cycle controlled by an electronic timer, it delivers clean, precise seals without the hassle of pricey Teflon covers over the sealing wires. An impulse sealing cycle is like a quick heat zap that seals the film together. Instead of staying hot all the time, the sealing wire only heats up for a short moment when needed. When you pull the sealing head down, a brief burst of heat through the sealing wires, melts the film just enough to create a clean, strong seal, and then it cools down almost instantly. It is cost saving, energy-efficient and fast way to ensure clean seals every time.

Each machine comes with an extra Spares Kit (including 2 sponges, 2 covers, and 2 wires) plus a 15-meter roll of Top Protection Strip to keep things running smoothly.

Operating Instructions

The product is placed into the centre of the folded film via the dividing plate. It is then moved to the left into the sealing area of the ‘L’ sealer. Lowering the sealing head activates the two sealing wires, cutting the film around the product. Since the trailing seal from the previous cycle forms the leading seal for the next pack, and the film is pre-folded on the roll with two open front edges, completing the seal encloses the product in a fully formed bag.

Frequently Asked Questions

1. What is an L Sealer and how does it work?

An L Sealer is a packaging machine that uses heated wires to seal products inside centre-folded polypropylene film. The “L” shape refers to the sealing bar configuration, which seals two sides of the film at once. It’s ideal for bakery goods because it creates a neat, professional finish while protecting the product.

2. What types of bakery products can I pack?

Our bakery L Sealers can wrap:

• Bread loaves, baguettes, baps, rolls
• Cakes, traybakes, flapjacks, scones
• Croissants, pastries, tea cakes, and savouries like sausage rolls or pies.
• You can also wrap non-bakery items if needed like clothes or pharmaceuticals.

3. What kind of film should I use?

We recommend centre-folded polypropylene film – either:

• Plain film for a crystal-clear presentation and longer shelf life
• Perforated film for warm products to prevent condensation

4. Can I seal warm products straight from the oven?

Yes – but only with perforated film, which allows steam to escape and avoids fogging.

5. What sizes of products can it handle?

The LS30 is our mid size model and can seal up to 300 × 300 mm with a 100 mm pack height – perfect for most bakery goods. We offer a smaller or larger machine option if required.

6. Is it suitable for high-volume production?

L Sealers are great for medium to high output in bakeries. If you’re packing hundreds of items a day, we can recommend the right model for your speed and volume.

7. How easy is it to use?

Very easy – simply place the product in the folded film, slide it into the sealing area, and lower the sealing head. The timer does the rest. No specialist training needed. See our YouTube deomnstration video for a detailed visual of how quick and easy packaging your products is.

8. How do I keep the machine clean?

Our machines feature stainless steel contact parts and a white epoxy finish for quick wipe-down cleaning.

9. Does it need a lot of maintenance?

No – L Sealers are low-maintenance. You’ll mainly need to replace the sealing wire occasionally, which is quick and inexpensive. Your machine will come with an additional Spares Kit containing 2 of each of the Wires, Tapes and Sponge Sets, as well as a 15m roll of Top Protection Strip to prolong the life of the base tapes.

10. Can it be moved around the bakery?

Yes – you can add an optional Floor Stand with locking castors for easy relocation.

11. Is it made in Britain?

Yes – our bakery L Sealers are proudly designed and manufactured in Whalley, Lancashire.
