We work in a factory-led model: our own factory handles core project communication, machine checking, assembly coordination, testing follow-up and after-sales support. When a project needs extra machine categories or specialized processing, we work with selected partner workshops and manage the project through one clear contact window.

We understand that. SUNSEE Machinery uses its own factory as the project base. For some machine types or special production steps, we also work with partner workshops that already have the right processing experience. This helps us cover more machine solutions without leaving the buyer to coordinate different suppliers alone. ### Own factory base Used for project communication, machine checking, assembly coordination, sample testing follow-up and service support. ### Selected partner workshops Used when a project needs a specialized machine type, special processing step or extra manufacturing capacity. ### One responsible contact The buyer communicates through SUNSEE Machinery, not a scattered group of unrelated suppliers. Why this is trustworthy ## Factory-style support without supplier confusion We do not simply forward catalogs. We review the product, check the packaging target, confirm the required machine route and coordinate the right manufacturing resources for the project. - One project contact from inquiry to delivery follow-up - Machine recommendation based on product sample and packing target - Factory involvement in checking, testing follow-up and service coordination - Partner workshops used only when they match the machine need - Clear discussion before quotation, so the buyer knows what is included - Factory photos, machine testing videos and sample packing results can be shared during the project Who we help ## We help buyers turn product samples into workable machine solutions SUNSEE Machinery works with manufacturers who need reliable equipment for 4 side sealing pouch packing, transdermal patch production, hydrogel patch packing, teeth whitening strip packing, rapid test kit pouch packing and zipper bag making. Many packaging projects cannot be decided by machine name only. Product shape, thickness, stickiness, pouch size, film structure, feeding method and output target all affect the final configuration. That is why our first step is always project checking. We ask the right questions before giving a machine route, so the quotation is closer to the buyer's real production need. What we supply ## Machine categories we can review for your project ### 4 Side Sealing Packing Machine For transdermal patches, hydrogel patches, cooling patches, rapid test kits, teeth whitening strips, medical sheets and other flat products that need sealed pouch packing. ### Patch Production Line Solution For patch projects that need adhesive confirmation, material checking, die cutting, feeding, 4 side sealing pouch packing and optional downstream packing. ### Zipper Bag Making Machine For flexible packaging factories making zipper bags, slider bags and resealable pouch formats with custom size and sealing requirements. ### Custom Feeding and Packing Options For projects that need automatic feeding, coding, cutting, punching, inspection, cartoning or connection with existing production equipment. Working process ## A simple process before machine recommendation 01 ### Send product information Send product photo, product size, pouch or bag size, material and target capacity. 02 ### Check the route We check whether manual feeding, automatic feeding, multi-lane packing or customized handling is more suitable. 03 ### Confirm responsibility We clarify which parts are handled by our own factory and which specialized parts may involve selected partner workshops. 04 ### Prepare quotation After key details are clear, we discuss samples, layout, delivery, testing and service. Factory video ## See how SUNSEE Machinery works with real machine projects This video gives buyers a direct look at our machinery work. More factory photos, testing videos and sample results can be shared during project discussion when needed. Before quotation ## What to send before we recommend a machine - Product name and application - Product photo, sample or drawing - Product size, thickness and surface condition - Pouch or bag size - Packaging material or film structure - Required speed or daily capacity - Manual feeding or automatic feeding requirement - Coding, cutting, sealing, punching or cartoning needs **Special note for patch projects:** For transdermal patch and hydrogel patch projects, please also send adhesive type, backing material, release liner and whether the coated roll is already available.
