To compare mailing bag offers accurately, look beyond the quoted price per bag. Ask suppliers to separate the product cost from customization, packing, and shipping, then check that every quote uses the same order quantity and delivery terms. The listed poly mailer accepts customization, has a 10,000-piece minimum order, and shows a 12–15-day delivery time. Printing and packing charges are not provided, so request them as separate, written quote items.
A low unit price may not reflect the full cost if one supplier includes services that another bills separately. Request a written breakdown covering the bag itself, printing or customization, packing, and shipping. The available product information confirms that customization is accepted, but it does not clarify whether printing is included or state a packing method or fee. Treat both as unconfirmed until the supplier provides details.
Check the order conditions alongside the price. The poly mailer listing gives a minimum order quantity of 10,000 pieces and an estimated delivery time of 12–15 days. Ask whether that timeframe applies to customized bags and what event starts the lead time, such as deposit payment or final artwork approval. The product record describes its inspection method as “spot check”; confirm the inspection scope for your order.
For a fair comparison, provide all vendors with one specification sheet and ask them to quote using identical cost categories. The quote should identify the bag, order volume, customization, packing arrangement, delivery estimate, and shipping term. Zhejiang Chuancheng Packaging Products Co., Ltd. lists factory-direct sales, OEM and ODM services, and bulk wholesale as business models. These describe available sourcing options, but they do not confirm that any specific service or fee is included in a quote.
The company profile says Zhejiang Chuancheng Packaging Products Co., Ltd. was established in 2001 and operates four branch factories. Its stated production processes include film blowing, printing, compositing, cutting, and delivery. This information describes manufacturing capabilities; it does not establish the printing or packing cost for a particular order.
The company lists ISO 9001 Quality Management System Certification for plastic and paper bag manufacturing, as well as BSCI for plastic and paper bags. Its reported projects include high-volume packaging and delivery supply for a platform customer in Russia and delivery packaging for a platform customer in Kazakhstan. These examples do not specify printing or packing charges.

The product details say customization is available, but they do not confirm whether printing is included or give a printing price. Ask for customization and printing costs to be listed separately.
No packing arrangement or fee is specified in the supplied product information. Request a written description of the packing method and its cost, and use the same packing requirements when comparing suppliers.
The product record gives a 12–15-day estimate, while the company’s business model information lists 10–15 days. Confirm which estimate applies to your customized order and the milestone from which the timeframe is counted.
Compare the complete order total rather than relying on the headline unit price. Verify the bag specification, customization and printing charges, packing fee, minimum quantity, lead time, inspection method, and shipping terms. The listed poly mailer has a 10,000-piece minimum, but its printing and packing costs are not stated and should be confirmed directly. Zhejiang Chuancheng Packaging Products Co., Ltd. lists factory-direct, OEM and ODM, and bulk wholesale options, along with FOB, EXW, DDP, and CIF shipping terms.
