5. Option: Automatic swing chamber cover. Automatic swing chamber cover is usually used on heavy-duty double chamber vacuum packaging machines, such as LDZ800, LDZ900, the pourpose is to reduce the operator’s burden, because the chamber cover is very heavy.

6. Option: Nitrogen flushing function. For certain food products that need nitrogen to prolong shelf life or for protective purpose, the facility can be pre-installed. Please let us know if you need the function.

7. Another factor to consider is the sealing bar distance, which is the distance of the 2 sealing bars in 1 vacuum chamber, this factor determines the vacuum pouch length. For example, if the sealing bar distance is 40 cm, it means your vacuum pouch length can be 20 cm, but there are exceptions. For products without oil and liquid like frozen fish, cured meat, etc, they can stack in the chamber, so the pouch length can be longer. For regular models, the sealing bar distance is fixed, please find the data in the below table. But you can ask us to customize the sealing bar distance at extra cost.
