Three-Side Sealed Pouch
Seeds and Agrochemical Products Industry
Customer Pain Points: Seeds and powdered pesticides are extremely sensitive to humidity and require protection against moisture and pests. Packaging for small-particle seeds must be easy to tear open and resealable after sealing.
Solutions
Three-side-sealed bags/center-sealed bags (roll stock): Used for small-sized packaging of grain, vegetable, and flower seeds. The aluminum foil structure provides complete protection against light and moisture, and can be equipped with easy-tear openings and laser micro-perforations (for breathable bags).
Stand-up Pouches and Accordion Pouches: Designed for large-volume pesticide applications, these offer ample capacity and can be equipped with carry handles for easy handling by farmers.
Anti-Counterfeiting and Traceability: Variable QR codes are integrated during bag production to help agrochemical brands prevent channel diversion and enable “one bag, one code” traceability.
Benefits for Customers: Prevents moisture intrusion, significantly reducing damage to seed germination rates; the roll stock is compatible with automated seed counting and packaging lines, improving efficiency.
Frequently Asked Questions
We provide free consulting services to solve your problems.
What kind of company are you?
We are a professional manufacturer with over 30 years of experience in the flexible plastic packaging industry, specializing in providing high-quality laminated packaging bags and rolls for the food, personal care, pet care, and agrochemical industries. From printing to bag manufacturing, we integrate design, production, and service under one roof, making us your trusted local partner for packaging solutions.
What types of packaging bags can you produce?
We offer a comprehensive range of core products, which primarily include:
Common bag types: three-side seal bags, center-seal bags, stand-up pouches, stand-up zipper pouches, and gusseted pouches
Functional Bag Styles: Spout pouches, eight-side-sealed bags, and irregular-shaped bags
Supporting Materials: Various center-seal and three-side-seal roll stock, suitable for direct use with automated packaging equipment
We also accommodate custom requests such as adding zippers, irregular die-cutting, clear windows, and vent valves.
What is an octagonal-sealed bag? What are its advantages?
Octagonal stand-up pouches, also known as flat-bottom pouches, feature a square, flat bottom with accordion-style folds on both sides, resulting in a total of eight sealed edges. Their greatest advantages are:
Excellent Display: They stand upright as steadily as a small box, with a smooth, crease-free main graphic that looks great on store shelves.
Larger Capacity: Compared to standard stand-up pouches, the accordion structure expands to accommodate bulkier contents.
Attractive appearance: With large-area double-sided printing, it perfectly showcases brand designs and enhances product value, making it an ideal choice for premium coffee, nuts, and pet food.
I'm not quite sure which type of bag to choose. Can you give me some advice?
Of course! That’s exactly what we specialize in. Please provide us with specific details about the contents, and we’ll offer tailored recommendations:
Liquids/pastes (e.g., laundry detergent, oyster sauce): We recommend spout pouches, which allow for precise dispensing, can be resealed, and leave minimal residue.
Solids that require repeated opening and closing (e.g., nuts, pet food): We strongly recommend stand-up zipper pouches, which preserve freshness, protect against moisture, and offer a great opening experience.
For high-value products requiring strong visual appeal (e.g., specialty coffee beans, bulk pet food): Octal-seal bags are the top choice and can be equipped with one-way vent valves.
For high-speed automated packaging lines (e.g., sunflower seeds, instant powders): Choose center-seal or three-side-seal roll stock for excellent adaptability and high efficiency.
What is the minimum order quantity for custom packaging bags?
We understand the risks involved in launching new products, so we’re very flexible when it comes to minimum order quantities. Typically, gravure-printed laminated bags have a certain minimum order quantity, which depends on the size of your bags. However, we can use digital printing to produce small-batch prototypes or initial production runs for you. This approach keeps costs under control and ensures colors that closely match mass-production results, helping you quickly test the market at a low cost.
How much does a prototype cost? How long does it take?
Cost: We charge a reasonable prototyping fee based on the bag style, size, and manufacturing process.
Turnaround Time: Samples of bags from our existing pattern library can be shipped out quickly; prototyping for new bag styles is typically completed within 7–10 business days after we receive the confirmed design draft.
