Not only is shrink wrap material used in packaging small items for selling in shops, it can also be used for a diversity of other things. To prevent minors from being able to view adult content in magazines, shrink wrap is regularly used to keep it closed while it is on the shelf. The plastic cannot be removed unless evidently done so and is therefore tamper proof. Another use is in the food industry, where products need to be safeguarded in a way that will prevent spillage. Cars and even houses can also benefit from shrink wrap materials, and it can be used to secure large shipments.
While there are many reasons to use the plastic from rolls, it is also available as shrink bags, which work on the same principles. The pre-formed bags mean that time is streamlined that would normally be spentgetting the material to the right size for shrinking. One of the values of a ready-formed bag is that it can be packed by one worker and sent to another to be sealed. Those with automated sealing machines can also heat-seal items in batches by sending them through the heat machine together.
The cost for these bags is very low, with the smallest size, suitable for a CD or VHS, costing around 2 cents per unit. The cost of operating the heating equipment is minimal, with the only other investments being property costs for the packing warehouse, and staffing costs. Companies often opt for this kind of shrink wrapping because it saves them money and protects their product.
Overall, using shrink bags is an ideal solution for many companies and has few drawbacks. Minor things to consider before choosing shrink wrap bags include staff training, the heat sealing equipment required and what size will be used for the product, For food safety, there are also FDA-compliant shrink wrap dome bags which are designed to be used with direct contact to food goods.
