The Main Sheet Fed Paper shopping Bag Machine Are Explained in Detail

1. Extremely high flexibility and adaptability

This is the core advantage of a single paper bag machine.

Wide material compatibility: can handle a variety of flat paper materials, including:

Ordinary kraft paper: white kraft paper, yellow kraft paper.

Specialty paper: Copperplate paper, art paper, laminated paper, laminated paper (used for moisture-proof or heat sealing), environmentally friendly paper containing recycled fibers, etc.

Non standard materials: It can even handle some thinner self-adhesive cardboard, lightweight cardboard, etc., which is difficult for paper bag machines to achieve.

Quick size switching: Changing the bag size (especially height) usually only requires adjusting the positioning gauge and some components, which is much faster and simpler than changing the entire paper roll width and repeating the overprint roller in a paper bag machine. Very suitable for small-scale, multi variety production modes.

Flexible process combination: It can be easily combined with preceding or succeeding processes. For example, using pre printed flat paper (such as through offset printing or digital printing) for bag making can achieve the highest quality pattern reproduction.

2. Excellent printing quality

Pre printed paper can be used: Single sheet paper bag machines typically use paper that has already been printed by single sheet offset printing machines. Offset printing is currently the most mainstream printing method, known for its high precision, color saturation, and delicate patterns. This is crucial for shopping bags, gift bags, and luxury bags that require high visual appeal from brand owners.

Spot colors and complex patterns: Spot colors, complex gradients, and fine text that can perfectly present the brand logo.

3. Low initial investment and operating costs

Equipment cost: In general, the purchase cost of a single sheet paper bag machine with the same production efficiency is lower than that of a drum paper bag machine with complex functions.

Plate making and sampling costs: As printing is an independent process, bag making itself does not require expensive printing rollers or flexographic plates, resulting in lower sampling and trial production costs and faster speeds.

Less material waste:

Using flat paper can directly utilize the scraps or specific sizes of paper from the printing factory, reducing raw material waste.

When debugging the machine, a single sheet of paper is fed, and the waste is usually several sheets of paper; However, during the debugging of the roll paper machine, a longer roll of paper will be wasted.

For ultra short version production (such as hundreds of bags), the comprehensive cost-effectiveness of single sheet paper mode is extremely high.

4. Relatively simple operation and maintenance

Intuitive operation: The mechanical structure for paper feeding and forming is relatively intuitive, with slightly lower technical requirements for operators and easier training.

Easy troubleshooting: The mechanical structure is not as complex as that of high-speed paper machines. When problems such as paper jams and breaks occur, they can be dealt with more quickly and the downtime is shorter.

Small footprint: Usually does not require a large unwinding and tension control system like a roll paper machine, and the overall structure is more compact.

5. Very suitable for short version and personalized production

Quick response: Very suitable for negotiating small orders, urgent orders, personalized customized orders (such as events, weddings, limited edition products). We received an order today and can start production tomorrow using pre printed or digitally printed paper from our inventory.

Variable data printing: can be combined with digital printing to achieve different QR codes, serial numbers, personalized information, etc. for each bag.
