Custom Printed Three Side Seal Pouches

Product Overview

A premade three side seal pouch has three sealed edges and an opening for filling. The receiving operation fills the empty pouch and makes the final seal. Start with the packed product, fill weight, a current pouch photo or drawing and quantity per artwork. Confirm which edge remains open, usable dimensions, filling clearance and the complete laminate before approving the specification. This is empty packaging supply, not product manufacture or contract filling.

Common Applications

• samples, sachets and single-serve portions
• powders, spices and seasoning
• candy, chocolate and confectionery

Material Options

• PET/PE — Possible structure for evaluation. Suitability depends on product, barrier target, sealing process and shelf-life tests.
• BOPP/CPP — Possible structure for evaluation. Suitability depends on product, barrier target, sealing process and shelf-life tests.
• PET/AL/PE — Possible structure for evaluation. Suitability depends on product, barrier target, sealing process and shelf-life tests.

Key Features

• Flat premade-pouch format reviewed separately from film formed and filled on an automatic line
• Printed artwork and seal layout reviewed on the same dimensioned drawing
• Opening, tear notch, window or zipper requirements checked against the actual pouch and filling route
• Final size and material confirmed using the product, filling conditions and representative samples

Printing & Finishing Options

• Printed layout — Identify the filling opening, three presealed edges, final seal, graphics and code area on the approved drawing
• Opening and reclosure — Review a tear notch or zipper where required; a zipper does not replace the original final seal
• Appearance — Confirm print colours, window and finish against the actual laminate and artwork; appearance does not prove barrier or shelf life

Technical Parameters

• State whether dimensions are external or usable internal dimensions, with units and seal-width allowances
• Identify the open edge, filling direction and clearance needed for the product or filling nozzle
• Check product density, shape, headspace and seal clearance with a representative filled sample rather than fill weight alone
• Review the final sealing method and the risk of powder, oil or product entering the seal area
• Confirm the complete laminate and intended filling, storage and use conditions; a familiar pouch shape is not performance evidence
• If the receiving line forms packs from a reel, review roll-film requirements separately rather than ordering premade pouches by appearance
• For vacuum-packing projects, identify the exact machine model and its pouch requirements. A three-side-seal shape does not establish compatibility with a chamber or external-suction machine; review the laminate, surface, usable size and final seal with the equipment instructions and a representative filled-pack trial
• State whether the filled pack will be chilled, frozen or heated. Vacuum packing, cooking and retort processing are separate requirements; confirm the complete structure and actual use conditions rather than assuming one approved bag covers all three

MOQ & Lead Time

Custom premade pouches are reviewed from 30,000 pieces per size and artwork, subject to final factory approval. Production timing is confirmed against the current factory schedule after the specification and artwork are approved.

Quality Control

• Material structure, thickness and roll or pouch dimensions checked against the approved specification
• Print color, registration, artwork position and surface finish inspected during production
• Seal strength, leakage or peel performance tested according to the packaging format
• Functional parts and actual filling or machine compatibility confirmed by appropriate samples

Common Problems

• Comparing external dimensions with usable filling dimensions without allowing for seals or a closure
• Leaving the wrong edge open or insufficient clearance for filling and final sealing
• Treating a zipper as the original heat seal or placing artwork across the final sealing area
• Substituting premade pouches for roll film without confirming the receiving equipment and supply format
• Ordering a vacuum-packing bag from its shape or material abbreviation without checking the exact machine and filled-product conditions

What to Prepare Before Inquiry

• Product, fill weight and filling method
• Current pouch photo or dimensioned drawing, with the filling opening identified if known
• Required external or usable dimensions and any closure or opening feature
• Known material, storage or protection requirements; list unknown fields for review
• Artwork status, printing variants and estimated quantity per artwork
• For a vacuum project: machine model, current pouch reference, intended storage or heating conditions, and any evacuation or final-seal problem

Pouch format and filled-sample decision matrix

Compare stand-up, flat-bottom, three-side-seal, side-gusset and roll-film formats, then record filled-sample checks.

Packaging project checks

Conditions, evidence, limitations and the next buyer action

Confirm the pouch geometry and the actual filling conditions before treating the format as suitable for a project.

1. 01

   Condition

   The project requires a two-panel pouch sealed on three perimeter sides without a gusset.

   Evidence

   Controlled format drawing and a reviewed physical sample.

   Limitation

   Front-view imagery cannot prove the absence of hidden folds or the final seal design.

   Next action

   Confirm geometry against the format QA record before quotation.

2. 02

   Condition

   Fill method, opening feature, seal contamination and pack-out are defined.

   Evidence

   Representative filled sample and agreed seal inspection records.

   Limitation

   The pouch format alone does not prove compatibility, barrier or shelf life.

   Next action

   Assign sample and production-stage checks in the project register.

These units organize project decisions; they do not prescribe a universal material, performance, compliance, shelf life, price, lead time or MOQ.
