A pouch for a small fastener kit and a bag for a larger metal component should not be selected on price per piece alone. The first needs to keep the contents together and easy to identify. The second may need more room at the opening, a different thickness and a packing method that protects the film from exposed edges.
For buyers sourcing PE bags for hardware, accessories or components, the most useful enquiry combines three things: the item being packed, the bag specification and the documentation requested by the customer.
Real Hengyi clear self-seal bag samples. Size and closure requirements should be checked with the intended contents.
Hangzhou Hengyi Packaging Material Co., Ltd. provides made-to-order PE packaging. Our available PE bag sample report includes RoHS substance testing, giving buyers a documented starting point for a technical discussion.
An LDPE self-seal bag is a candidate when the contents need to be removed and the opening closed again. The usable width, usable height and closure should be checked with the actual contents. If a kit contains screws, brackets or other sharp edges, test the proposed packing arrangement rather than assuming a thicker bag will solve every problem.
An adhesive-closure bag is a different option. The flap dimensions, adhesive arrangement and surface conditions matter. The packing operation should establish whether the closure performs as required; a film test alone does not demonstrate adhesive performance.
A bag with holes needs a drawing that defines the number, diameter and position of the holes. The intended function should be agreed explicitly. A visible hole is not, by itself, evidence that the bag is designed for hanging, ventilation or another particular use.
Hengyi's current custom product options include LDPE self-seal bags and LDPE or HDPE options for adhesive and perforated bags, subject to the agreed product specification. These are custom-order options, not a statement of ready stock.
RoHS addresses restricted substances in electrical and electronic equipment. A packaging supplier's RoHS-related substance report can be relevant to a customer's purchasing specification, but it should not be presented as automatic certification of every plastic bag. European Commission: RoHS Directive.
Hengyi's SGS report SHAPH26023536201, dated 6 August 2026, identifies the submitted sample as PE BAGS, with transparent film as the tested part. It records a Pass against the RoHS substance requirements listed in the report.
For your order, compare that sample description with the proposed material, print, closure and other components. A report for the film does not automatically establish the results for added ink or adhesive. The document should support an identifiable specification.

Provide the dimensions and weight of a complete kit, not only its largest individual part. Show any protruding corners. Tell us whether the bag sits inside a box, is handled individually or is opened during assembly.
When reviewing a sample, check loading, closing, identifying and removing the contents. Include the actual packing sequence. These observations help refine a bag specification before a larger order is discussed.
Send Hengyi a product photograph or drawing, the preferred bag size, single-wall thickness, quantity and closure requirements. If your customer asks for RoHS-related evidence, include the requested test items or purchasing specification so we can review the relevance of the available report.
Tell us what goes inside the bag. We can discuss the packaging and its documentation together.
