Mostly positive. However, we need to classify the diverse situations and answer as follow.
1) In case, just packaging dimension (the shape of packs) changes with the same product.
Its formers have to be altered along with the altered dimension. ‘Formers’ are metallic patterns in the module of ‘forming die’ to thermoform film into designed cavity. The packaging dimension shall not exceed the spatial accommodation of ‘forming die’.
In the fixed size of the die, if the unit pack becomes bigger, the output number of one cycle will decrease whereas the unit pack becomes smaller, the number will increase accordingly.
In case of bulk packaging, if the buyer needs to differentiate the volume of products, we can give a solution with one machine to alter packaging volume in two grades, for example, between 1kg and 2kg. The principle is adjustment of thermoforming depth with the same width and length. In this case of dual volume of bulk packaging line with one set of our machine, operators can manipulate so simply and easily to change the production every morning and afternoon.
2) In case, the packaging dimension (the shape of pack) is same and the product changes.
If you change only product with the same shape of packs, thermoforming packaging machines would not need modification. However, you may have to search for new optimal vacuum degree to set for the new product.
3) In case, the phase of the product changes, for example, from dry and solid products to liquid.
The conversion of packaging mode is possible but it is hard and expensive job. It is better for customers to make the confirmed decision on the mode of packaging – normal vacuum, modified atmosphere, liquid, flexible or rigid, etc. before placing an order. It is up to ‘film’ to thermoform. It will be OK if the film is qualified for radio wave safety.
