One-Stop Flexible Packaging Solution | XIAOPAI
One-Stop Flexible Packaging Solution from XIAOPAI
Flexible packaging is everywhere — from snack bags and coffee pouches to pharmaceutical sachets and industrial wraps. A complete flexible packaging line moves raw plastic granules through film blowing, lamination, printing, slitting and rewinding, then finally to finished rolls or pouches. XIAOPAI supplies a one-stop flexible packaging solution that covers every stage of this workflow, helping converters set up or expand their production with matched equipment and reliable support.
What Is a One-Stop Flexible Packaging Solution?
A one-stop solution means a single equipment partner can supply the key machines needed to turn raw material into a finished flexible package. Instead of buying machines from multiple vendors and trying to make them work together, converters work with one supplier who understands the full line and can match each unit to the next process step. The main stages are:
Raw material production — plastic granules are melted and extruded into film.
Film blowing — the film is inflated and cooled to form thin, strong sheets such as BOPP, PET or PE.
Lamination — two or more films are bonded together to improve barrier, strength and appearance.
Printing — the laminated film is printed with branding, product information and colors.
Slitting and rewinding — wide printed rolls are slit into narrower rolls for bag-making or packaging lines.
Other finishing equipment — such as paper tube cutting, bag making and pouch forming machines.
XIAOPAI's one-stop flexible packaging line covers these stages with compatible equipment, making installation, commissioning and after-sales support simpler.
Stage 1: Raw Material and Film Blowing
The process starts with chemical plastic granules. A film blowing machine heats and extrudes the granules through a circular die, then inflates the tube into a thin film bubble. The bubble is cooled, collapsed and wound into a roll. Common films produced at this stage include BOPP, PET, PE and CPP. These single-layer films often need additional barrier properties, which is why the next step is lamination. Learn more about the basics of flexible packaging from the Wikipedia flexible packaging overview.
Stage 2: Solventless Lamination — The Core of the Line
Solventless lamination bonds two or more films using a reactive polyurethane adhesive that cures without solvent. It is now the preferred lamination method for food and pharmaceutical packaging because it produces no VOC emissions, uses less energy than solvent-based lines and meets strict environmental regulations.
XIAOPAI is the authorized global distributor of Sinstar solventless laminating machines. Our solventless laminating machine selection guide explains how to choose between the WRJ Fi9, WRJ i9 and WRJ S1 series. Key models include:
WRJ Fi9 solventless laminating machine — a versatile unit for general flexible packaging.
WRJ i9 solventless laminating machine — stable two-layer lamination at higher speeds.
WRJ S1 digital solventless laminating machine — digital control for short runs and quick changeovers.
Choosing the right laminator depends on web width, line speed, substrate combination and whether you run long, stable jobs or frequent short runs. Our guide and product pages detail each option.
Stage 3: Printing for Flexible Packaging
After lamination, the multi-layer film is sent to a printing machine. Flexographic and gravure printing are the most common methods for flexible packaging. High-quality printing ensures brand colors, product labels and regulatory information are clear and consistent across large volumes. The printing unit must be matched to the film width, tension control and registration accuracy needed for your target market.
Stage 4: Slitting, Rewinding and Other Finishing Equipment
Printed rolls are usually too wide for downstream packaging lines. A rewinding slitting machine cuts the wide roll into multiple narrower rolls with clean edges and consistent tension. This step is critical for bag-making machines, form-fill-seal lines and pouch converters. XIAOPAI also supplies other finishing equipment such as paper tube cutting machines and rewinding units to complete the production line.

Frequently Asked Questions
What products can be made with this one-stop line?Food packaging, snack bags, coffee pouches, pet food bags, pharmaceutical sachets, detergent pouches, industrial flexible wraps and many other laminated packages.
Can I start with just one machine, such as a laminator?Yes. Many customers begin with a solventless laminating machine and expand the line later. XIAOPAI can plan the line so each new machine fits the existing workflow.
Which regions does XIAOPAI serve?XIAOPAI supplies flexible packaging machinery globally. We support customers with English documentation and export packing. For more details on flexible packaging materials, see the Plastic Films overview on Wikipedia.
