Finished plastic bags and roll film are two ways in the production of flexible packaging plastics, one is to leave only one mouth and the rest of the edge is sealed into a bag, and the other is the packaging roll film with a paper tube in the center. So what's the difference between these two packages? How to choose more cost-effective?
First, plastic packaging bags are finished packaging bags
The finished plastic bags produced on the market are generally sealed with the rest of the sides, leaving only one mouth. When customers use plastic bags, they only need to seal the products after they are put into plastic bags. Some products that need to be vacuumed use vacuum packaging bags, and the work of vacuuming and sealing can be completed on the vacuuming equipment, which is very convenient.
Plastic bag manufacturers generally calculate the minimum order quantity and quotation of plastic bags according to "one", and the payment for goods to you is also calculated according to "number".
Second, plastic packaging film is a semi-finished plastic packaging bag
Roll film in the packaging industry does not have a clear and strict definition, just a conventional term in the industry, simply speaking is the rolled packaging film, for packaging manufacturers is only less than the production of finished bags, its material type is also consistent with plastic packaging bags, common PVC shrink film roll film, opp roll film, pe roll film, pet protective film, Composite roll film, etc. Roll film is used in automatic packaging machines, such as common bag shampoo, some wet wipes, etc., using this packaging mode. The cost of rolling film packaging is relatively low, but it requires an automatic packaging machine.
When plastic packaging film is delivered to customers, customers need to have their own automatic filling machine, plastic packaging film in the automatic packaging machine to complete the whole process of bag making, filling, sealing, coding.
In summary, finished plastic bags and rolled film are different in the following five aspects:
Appearance: The finished plastic bag is a plastic bag that has been made, usually in the form of a single bag. Roll film is a roll of plastic film, usually with a paper tube as the core of the roll.
Production stage: The finished plastic bag is the end product that has gone through the bag-making process and can be used directly. The roll film is the packaging film of the printing composite into a roll, and the bag making process is not carried out in the printing plant, which is a semi-finished product.
Customization: Finished plastic bags are usually calculated in accordance with the "one" to calculate the minimum order quantity and quotation. The roll film is in accordance with the "kg" to calculate the minimum order quantity and quotation, different widths and different thicknesses of plastic bags in the minimum order range of finished bags may vary a lot.
How to use: the finished plastic bag can be used directly, and the rolling film requires customers to have their own automatic filling machine, in the automatic packaging machine to complete the whole process of bag making, filling, sealing and coding.
The finished product effect: the final product effect of plastic packaging bags and plastic packaging film is the same, generally a particularly small plastic packaging bag, a bag that needs to be inflated or resterilized during packaging, a packaging process that requires very high packaging efficiency and a relatively high degree of automation, etc. This type of product is suitable for the form of plastic packaging film.
Large enterprises equipped with automatic packaging machines can choose to roll film and fill it by themselves, which is more cost-effective. To customize a smaller number of products, it is more convenient and cost-effective to choose finished plastic bags.
