What is the process for custom packaging bag production?

It is undeniable that small packaging bags occupy a very important position in many manufacturing enterprises. Many food factories, garment factories, hardware factories, electronics factories, and cosmetics factories all need large quantities of exquisite packaging bags. However, many times, existing packaging bags are not satisfactory, either because the quality is too poor or they cannot meet product upgrade needs, urgently requiring custom-made packaging bags that can better meet the enterprise's development needs.

How does the custom packaging bag process work? We believe this is what many enterprises want to understand. Today, Shunxingyuan Packaging, a professional flexible packaging manufacturer, will provide a comprehensive interpretation of the custom packaging bag process.

1. Packaging Bag Design Files

Some enterprises have in-house UI designers or cooperate with other design companies. In such cases, these enterprises can provide the design drawings to the packaging bag manufacturer, who will then perform color printing layout design. However, some enterprises do not have UI designers. In such cases, these enterprises need to prepare drafts in advance and provide them to the packaging bag manufacturer for design.

The drafts to be prepared will vary by industry but are largely similar. They mainly include essential printing information: product name, logo, trademark, main ingredients (can be named as formula, food formula), product registration barcode, net content, manufacturer information (including full manufacturer name, license number, and address), QS mark or certificate number (CS mark implemented in 2017), product standard number, storage method, usage instructions. If there are allergens or unsuitable usage situations, precautions need to be indicated, as well as the specifications of the packaging bag, the desired bag type and material, the unwinding direction of the packaging film, common theme colors, an overview of the enterprise's culture, common background images, and the desired theme to express.

All the above draft information must be carefully checked for typos. Then, the packaging bag manufacturer will proceed with the design, and the designed drawings will be submitted to the client for confirmation. The client needs to carefully re-verify the information on them.

2. Packaging Bag Gravure Plate Making

The packaging bag manufacturer will perform printing layout and print plate production based on the design drawings, materials, and process requirements. This typically takes about 5-6 working days.

3. Printing and Lamination

Different equipment has different printing speeds and effects, with high-speed machines having the highest printing efficiency. After printing, other processes such as aluminum washing, hot stamping, and surface lamination are performed. This is followed by the lamination of the heat-seal layer and other functional film layers. After lamination, drying and curing are required. Once laminated, the lamination quality is inspected, and any defective areas are marked, followed by slitting and rewinding.

4. Bag Making

The slit and re-rolled film is placed on the corresponding bag-making machine for bag production. For example, a zipper bag-making machine can produce stand-up pouches with zippers, eight-side seal bags, etc.

5. Quality Inspection

During quality inspection of packaging bags, Shunxingyuan Packaging removes all non-conforming products, ensuring 0 non-conforming products leave the factory, and only packages qualified products.

6. Delivery Inspection

Logistics shipping is usually chosen, but express delivery may also be used in urgent cases. The finely printed packaging bags are sent to the client for inspection.

In summary, the custom packaging bag process is divided into the 6 steps above. Delivery can be completed in approximately 7-15 working days from the date of design drawing confirmation. If the order quantity is large, the production period will need to be extended.
