How to Make A Stand Up Pouch? Explore Manufacturing Process

In today’s consumer market, stand up pouches have become the preferred packaging solution for many industries such as food, daily chemicals, pet products, and agricultural products due to their excellent shelf display capabilities, excellent sealing, and easy transportation and storage.

As a professional flexible package manufacturer, Stanley provides a one-stop stand up pouch solution from design, material selection to production, quality inspection, and delivery. This article will introduce the entire process of Stanley’s stand up pouch production in detail, so that you can have a clear understanding of every step of customized packaging.

Overview of stand up pouch structure

Stand up pouches are a type of packaging pouch that can stand independently with the help of the bottom structure. They are mainly made of multi-layer composite films and have the following typical characteristics:

• Bottom corner sealing: forming a stable triangular support structure so that the bag can stand on the shelf when it is unopened.
• Composite structure: common such as PET/PE, PET/AL/PE, PET/VMPET/PE, etc., used to achieve moisture-proof, oxygen-proof, UV-proof and other functions.
• Expandable functions: zippers, nozzles, tear-off notches, hanging holes, anti-counterfeiting labels, etc. can be added to improve user convenience.
• Wide range of applications: used in food (nuts, coffee, condiments), liquids (laundry detergent, juice), dry goods, pet food, etc.

Stanley’s stand up pouch customization and production process

Stanley has a mature technical system and advanced production equipment, supporting small batch customization to large-scale mass production. The following is our standardized and systematic process:

Customer demand communication

Our first step is to fully communicate with customers to ensure that we accurately understand the customer’s requirements for the function, appearance, and usage scenarios of stand up pouches. The main contents include:

• Product type and use
• Capacity and size specifications (such as 100g, 250g, 1L, etc.)
• Material requirements (whether it needs to be blocked, UV-proof, frozen, etc.)
• Printing color and design artwork (CMYK/Pantone color value)
• Special requirements (such as matte film surface, paper texture, metallic luster, etc.)

Structural design and artwork confirmation

Customers can provide design files (AI, PDF format), and we can also provide structural suggestions and layout services to ensure that the pouch type is coordinated with the visual effect.

If there is no design artwork, our design team can assist in completing pattern development, brand element arrangement and text specifications.

We can also produce electronic renderings or provide digital proofing according to needs for customers to confirm the color, material and functional structure.

Printing and lamination

After the design is confirmed, the printing process begins. Stanley is equipped with a high-speed gravure printing machine that supports:

• Multi-color fine printing (up to 10 colors)
• Special effects such as full pattern, partial hot stamping, cold silver stamping, etc.

After printing, the materials are laminated. Choose according to your needs:

• Dry lamination
• Solvent-free lamination
• Extrusion lamination

This step ensures that different functional material layers fit tightly and enhances physical properties (waterproof, oil-proof, gas barrier, etc.).

Ripening and slitting

The laminated materials need to be cured (48-72 hours) to allow the adhesive layer to fully cure and improve the stability of the material. Subsequently, the material is precisely slit into the roll width required for production, ready to enter the next bag making process.

Pouch making and molding

Pouch making is a key step in achieving the structure of a self-supporting bag. We use automatic high-speed bag making machines to:

• Heat-seal the bottom of the bag and punch the corners to form a self-supporting structure
• Install functional accessories (zippers, nozzles, hanging holes, etc.)
• Add easy-tear edges and edge embossing to enhance consumer experience

Quality inspection

We implement a number of standardized quality inspection procedures, including:

• Heat-seal strength and airtightness testing
• Drop test, freezing test
• Printing deviation and color stability testing
• Appearance inspection (whether there are bubbles, wrinkles, printing ink leakage, etc.)

Each batch of goods is accompanied by an inspection report and strictly implements factory standards.

Packaging and delivery

Qualified products are packaged as required, and you can choose:

• Bulk packaging
• Packaging according to customer-specified quantities
• With labels, barcodes, QR codes and other information labels

We support global logistics distribution, and the regular production cycle is 12-18 working days (depending on the complexity and quantity of customization).
