Vacuum bags are generally a packaging method that adds products to an air-tight packaging container and evacuates the air inside the container to achieve a predetermined vacuum degree in the sealed container.
Vacuum bags are widely used in food packaging, pharmaceutical raw materials, bio-chemical, chemical raw materials, pharmaceutical intermediates. Vacuum bag has good water barrier, oxygen barrier, shading, and other advantages. According to the packaging needs, it can be customized with different specifications and styles, and can be made into three styles: three-side sealed bag, back sealed bag, self-supporting bag , organ bag and so on.
Customizing vacuum packaging bags is a very rigorous work. A good packaging product needs to fully consider the needs of production, packaging, transportation, sales and other links. Changzhou Haorun Packaging Materials Co., Ltd. is a professional custom-made vacuum bag manufacturer . The company has a professional R & D and design team, which can provide customers with bag-type design and packaging material options for free to create unique vacuum bags for your products.
When ordering vacuum bags, customers first have the price problem, but considering the different vacuum packaging bags required by each customer, such as thickness, size, material and printing color, the price is also different. Therefore, please be sure to specify the needs when ordering vacuum packaging bags, so that the accountant can accurately calculate the price of vacuum packaging bags.
Custom-made vacuum packaging bags can first confirm the size of the bag, the more feasible method is to refer to the products of the same industry. You can go directly to some distribution channels such as supermarkets to purchase products with similar contents and then measure the basic dimensions of the bag. These dimensions include the width of the bag, the height of the bag, and the width of the edge of the bag. Some special bag types, such as folded bags and flat bottom bags, also need to measure the dimensions of the folded edges and bags. The unit of measurement is generally millimeters.
Customized vacuum bags can be confirmed by the material of the bag. Common composite materials of composite film bags are:
(1) two layers: BOPP / LDPE, BOPA / LDPE , PET / CPP, BOPP / CPP, BOPP / P E, PA / CPP, BOPP / VMCPP, BOPP / VMBOPP
(2) Three layers: BOPP / V M OPET / LDPE, BOPP / V M OPET / CPP, BOPET / V M OPET / CPP, BOPET / V M OPET / LDPE
The confirmation of the material of the vacuum packaging bag may seem simple, but an ideal packaging material needs to fully consider the following aspects: the adaptability of printing; the barrier performance of the material, including water barrier, oxygen barrier, light barrier, etc .; Heat sealing performance and bag making difficulty. In addition, the confirmation of the material of the vacuum packaging bag also needs to consider the weight of the packaging content and the form of the packaging content, such as powder, granules or liquid. In addition, the confirmation of the material of the vacuum packaging bag needs to consider the performance and characteristics of the packaging equipment used in production. In addition, there are other requirements for packaging materials during transportation and sales. Therefore, for the sake of stability, the confirmation of the material of the vacuum packaging bag is best to be designed by a professional manufacturer. Changzhou Haorun Packaging Materials Co., Ltd. has complete and advanced testing equipment and test instruments, and has many years of experienced R & D personnel. It can recommend suitable packaging materials for customers for free.

(1) Gravure printing requires CorelDRAW or  Adobe Illustrator format files;
(2) In the pattern design, if the relevant pattern country has regulations, the relevant requirements of the national regulations should be followed (such as: bar code, net content and height of explanatory text, QS, and related national regulations, etc.);
(3) If the registered trademark is included in the pattern design, it is necessary to customize the company to provide the registration certificate or use authorization of the registered trademark.
(4) The lines of the iconic pattern should be thickened as much as possible. If there are white borders, it should not be less than 0.5mm, so that the printing is clear!
The production cycle of custom-made vacuum packaging bags is generally about 15 days (such as the production cycle of transparent vacuum packaging bags without printing patterns is about 12 days), plus manuscript confirmation and printing plate making usually takes about 7 days, and logistics transportation generally 2- 3 days. Therefore, custom vacuum packaging bags from contract signing to product delivery (which is also related to the order volume) generally require a delivery time of about 25 days.
 Custom vacuum bag production process is generally: graphic design - client confirmation document - the plate - printing (check sample) - Composite - curing - slitting - Bag - test - the factory (delivery).
