Sealing Requisites for Different Products

Sealing is one of the processes of protecting and it is applied in various ways in packaging industries. Be it food or chemicals or cosmetics, proper sealing is required to maintain the shelf life of the products inside. Every sealing work is composed of a range of methods such as cap designing, choosing appropriate sealing material that stays compatible for the product inside, estimating the size and dimension of the fastening products and finally an apparatus that can perform the sealing operations automatically. In addition, the type of containers or packaging materials is to be analyzed before choosing the closing up elements. For example, glass containers, pouches, plastic bottles and containers, sheet metal boxes, etc have to be sealed differently and with different methods such as caplugs, screwing caps, threaded caps, tips, etc.

Most Appreciated Methods of Screwing Bottles
Bottles, especially those that are made of glass are delicate products for which screw lids are found to be ideal option of fastening. With the invention of new closing up equipments, the risk involved in conventional sealing methods has been considerably reduced. Glass containers are fragile items that need to be capped carefully; hence, screw fastening apparatus will stay a suitable and most convenient option. In addition, these locking equipments are moderate in size and can be installed expediently. Moreover, the size, volume of the glass containers and the funds available the screwing specifications can be decided.  For example, a manual screw sealing apparatus is a cost effective option for small scale industries, a semi automatic and automatic gadgets are suitable options for moderate and high packaging requirements. The process of screw sealing has been converted to an unimaginable process with the help of latest machineries and subsequently reduced the man power requirement also. Thus these screwing gadgets are considered as well-suited for glass and plastic bottles.

How to Avoid the Risk of Damages while Handling Caps for Screwing?
Handling the containers is more important while applying the capping process. In one way, the product inside should not get contaminated, and on the other way the containers should be handled properly to avoid the risk of breaking. As far as automatic fastening apparatus is concerned, special specifications are provided for careful sealing process management over glass containers such as,

  • Good speed of fastening caps is very important, as the speed should go compatible with the material of the container.
  • Frequency of capping process should be controlled by the motor.
  • Diameter adjustment possible in capping process which helps to fasten different shapes of glass or plastic containers.
  • Presence of pneumatic and electrical components for speedy, durable and reliable capping performance.
  • Provision of Flexible control panels for easy operation
  • Automatic removal of reverse threading.
  • Simple adjustment facilities to match the capping process in accordance with the container shape and size.

 

Conclusion
While considering the screwing process, purchasing suitable machinery has to be done after complete analysis of the production level, types of containers that will be used, and the compatibility of the sealing product with the force applied by the apparatus. Hence, making a thorough enquiry with the manufacturer of the equipment will fetch you the right kind of machinery.
