Dongguang County Sansheng Plastic Packaging Co., Ltd. is one of the leading manufacturers and suppliers of custom back-sealed accordion bag in China, featured by quality products and low price. If you're going to buy bulk durable custom back-sealed accordion bag, welcome to get quotation from our factory. We also accept customized orders.
Our factory specializes in custom-made back-sealed accordion bags, integrating back-sealing technology with an accordion expansion structure. The process is mature and stable. The centrally located back seal features neat lines, high heat-pressed adhesion strength, and is resistant to tearing and splitting. The accordion design on both sides allows for flexible extension, providing excellent expansion capacity and preventing deformation even with large-capacity filling. Materials can be selected according to requirements, offering excellent barrier properties, preventing moisture and dust, and protecting the contents. We support personalized customization of specifications, thickness, printing patterns, and logos. We accept orders of all sizes, with strict quality control and stable delivery. Widely applicable to packaging bulk goods such as grains, feed, dry goods, and industrial materials, these bags stack neatly, facilitate storage and transportation, and offer excellent cost-effectiveness, making them an ideal choice for bulk purchases.
Ordinary simple packaging bags on the market have a loose structure, lack a centralized back seal and accordion expansion structure, resulting in uneven surfaces after filling. They completely fail to meet the export production standards of Custom Back-sealed Accordion Bags. Cross-border shipping has limited container space; ordinary packaging bags cannot be stacked neatly, easily wasting container space and increasing logistics costs. Meanwhile, the uneven sealing can easily lead to problems such as bottom cracking, minor powder leakage, and oxidation due to moisture when loading granular or powdery materials, causing unnecessary after-sales losses for foreign trade merchants.
Our Custom Back-sealed accordion bag is a special bag type designed for foreign trade, specifically for neat packing and large-capacity loading. It adopts a central back seal and two-sided accordion structure, with a straight and tight back seal. When the bag is opened, it is square and flat, and when filled, it maintains a square shape without bulging. Compared to ordinary flat bags, it has a larger capacity, more even stress distribution, and stacks neatly without taking up much space, greatly improving packing utilization. It is ideal for large-volume standardized cross-border shipments and neat warehouse storage.
Regarding size customization, the Custom Back-sealed accordion bag supports full-range size customization to adapt to various material loading needs. Standard sizes cover mainstream specifications such as 12*28cm, 15*35cm, and 20*40cm, meeting different scenarios such as small sample packs, regular retail packs, and large-capacity industrial bulk packaging. It supports customization of special widths, bag heights, and accordion opening angles. The bag thickness is flexibly adjustable; thinner versions are suitable for lightweight dry goods, while thicker, more durable versions are suitable for heavy materials and hard granular materials, truly achieving customized solutions to precisely suit various export products.
All Custom Back-sealed accordion bags are made of export-compliant composite materials, with thick and uniform material usage, eliminating issues such as falsely advertised thickness or cost-cutting. The bag body is tensile-resistant, pressure-resistant, and tear-resistant, and is not easily torn when fully filled, easily handling complex storage and transportation conditions such as long-distance sea freight and multi-layer stacking. Excellent barrier properties effectively isolate air, moisture, and dust, firmly locking in product quality and effectively preventing dry goods, powders, grains, and other materials from becoming damp, clumping, oxidizing, and deteriorating, making them suitable for long-term global warehousing and cross-border sales.
The production process strictly follows international export standards, with even and tight back seal stitching, neat and symmetrical accordion folds, and balanced overall stress, preventing localized chipping, gaps, or leakage. Supports high-definition gravure color printing, and can be customized with multiple foreign language instructions, brand logos, and product parameters. Printing is clear, durable, abrasion-resistant, and colorfast. Matte, glossy, frosted, and windowed finishes can be added to meet the diverse export compliance standards and brand packaging needs of various countries.
Overall, this back-sealed gusseted bag is a high-performance, cost-effective choice for bulk export shipments. Its well-proportioned shape, ample capacity, and stable load-bearing capacity save on logistics and packing costs, while reducing after-sales issues such as powder leakage, damage, and moisture damage from the source. Suitable for various export scenarios including dry food, cereal powders, and industrial materials, its robust and durable quality ensures the quality of every cross-border order.
