HP-250D/B/C-PS Peel-and-Seal Pocket Envelope Making Machine Overview

The peel and seal pocket envelope making machine from HAOXING is the HP-250D/B/C-PS model. This HP-250D/B/C-PS series makes open-end pocket envelopes with an inline peel-and-seal closure. Feeding, folding, gluing, peel-and-seal application, counting and delivery are combined in one process. The information below summarizes the manufacturer's published features and technical figures; please confirm the exact machine offered for your application.

How the HP-250D/B/C-PS Fits Your Production

For an envelope-production project, start with the finished format, flap orientation and closure method. Specify the paper stock, finished dimensions and expected output before choosing a model. If an existing line already performs part of the job, check whether you need a full forming machine or only a finishing station. A sample blank and an example of the desired finished envelope help the manufacturer review the tooling and configuration.

For this envelope-making model, HAOXING specifically lists servo-controlled peel-and-seal application; air-suction feeding and accurate paper positioning; three sizes for different pocket-envelope formats. These details describe the model family and are a basis for discussion, not a promise that every optional function is included. Confirm the configuration, tooling and materials on your quotation.

Where the table gives several values separated by model, each value belongs to the corresponding variant in the same order. Do not treat the largest figure from one variant as a specification for all variants.

Published values may vary by configuration, material and operating conditions. Request a current technical sheet, production trial and final machine drawing before ordering or preparing factory utilities. The figures here are for model comparison and are not a substitute for the confirmed quotation.

Production Planning and Quality Checks

During a trial, assess sheet feeding, register, fold alignment, adhesive placement and delivery quality using your actual stock. Published production rates are reference figures, not a guarantee for every paper and size. Ask for the operating conditions behind a quoted rate and verify the result on your own material.

Before selecting the HP-250D/B/C-PS, provide the finished-product dimensions, input material specifications, target output and a sample of the product you want to make. HAOXING can then check whether the published range covers your application and identify any optional systems or changes needed. Ask for an agreed test method, including how acceptable quality and output will be measured.
