1. Product Overview

Our Square Whiskey Glass Bottle bottles are tailor-made for bulk distributors and commercial packaging businesses, widely used for whiskey, brandy, vodka and other spirit packaging solutions. Every piece follows unified industrial sizing standards, delivering steady structural performance and tight tolerance control across batches. We also provide full customization support, perfectly catering to bulk purchasing needs from global distributors, independent brand owners and packaging wholesalers.

2. Core Product Specifications

2.1 Basic Dimension Data

Our standard stock size is 750ml, with customizable volumes ranging from 100ml up to 1,000ml. Volume deviation is controlled within ±2ml for consistent filling results. A single empty bottle weighs 580g with a tolerance of ±5g; all finished batches share identical dimensions for uniform stacking and processing. We produce these bottles with high-purity food-grade crystal clear glass. The material is free of internal impurities, offers excellent light transmission and delivers neat, symmetrical bottle shaping.

2.2 Material Safety & Certifications

All glass raw materials adopt lead-free, BPA-free formulas. The material features stable chemical inertness, so it won't alter the flavor or hue of liquor stored inside. Our products comply with US FDA food contact standards, EU LFGB food grade requirements and REACH environmental regulations. We can supply complete batch test reports to help overseas clients clear customs and complete local product filings.

2.3 Structural Advantages

The bottle adopts an integrated square molding design. Embossed textures on outer walls improve grip during handling while building unique shelf recognition. We thicken glass at high-stress bottle wall areas, with minimum wall thickness reaching 3mm for enhanced durability. Standard thread necks fit most mainstream automatic filling, capping and labeling machines sold worldwide. The widened flat reinforced base keeps bottles stable on shelves and allows safe multi-layer pallet stacking for sea freight.

3. Key Benefits for Bulk Buyers

3.1 Logistics & Cost Savings

The streamlined square shape maximizes container loading efficiency for palletized shipments. Each pallet holds 72 bottles, arranged as 12 pieces per layer across six layers. Compared to irregular uniquely shaped bottles, this optimized structure cuts overall ocean shipping costs by 15 to 20%. Custom internal dividers are included in packaging to keep transit breakage rates below 0.3%.

3.2 Compatibility with Automated Production Lines

All dimensional tolerances are held within ±1mm. This tight consistency lets clients run the bottles on fully automatic filling, sealing and labeling lines without repeated machine calibration, cutting down production downtime and labor expenses for large bulk orders.

3.3 Strong In-Store Selling Performance

Ultra-transparent glass fully showcases liquor color and texture to shoppers. Distinct embossed body detailing helps our wholesale partners stand out against competing products on retail shelves and drive higher sales volumes.

Production Facility Setup

Our factory runs 15 fully automated glass production lines with high-efficiency manufacturing equipment. Separate dedicated workshops are built for decal processing, baking curing and silk screen printing work.

4. OEM & ODM Customization Support

4.1 Customizable Options

We offer bespoke mold development, custom bottle contour redesign and custom dimension adjustments. Available surface customizations include silk screen printing, hot foil stamping, frosting, spray coating and body emboss/deboss detailing. We can match any Pantone color shade for bottle bodies and matching accessories, alongside a full lineup of closures: plastic screw caps, natural corks and aluminum caps.

4.2 Order & Lead Time Rules

Custom mold orders require a minimum run of 6,000 pieces. For existing stock items, we accept bulk purchases without strict minimum quantity requirements. New custom molds take 7 to 15 working days for development and trial production. Once samples are confirmed, mass bulk orders ship within 10–20 working days, supporting steady long-term repeat orders for wholesale partners.

5. Factory Capacity & Strict Quality Management

5.1 Production Scale

We operate 15 full-automatic glass forming lines, with total annual output surpassing 300 million glass bottles. For this 750ml square bottle model alone, our stable daily output hits over 50,000 units. We can easily fulfill extra-large bulk orders and support fixed long-term supply contracts. The full production chain stays in-house: mold fabrication, glass forming, annealing heat treatment and all post-print decoration steps, no outsourced processing.

5.2 Full-Set QC Standards

Every bottle passes automated camera inspection to filter out defects including air bubbles, surface cracks and dimension inconsistencies. Finished goods undergo 1.2 bar pressure resistance and full leak testing before shipment. Our facility holds ISO 9001 quality management and ISO 14001 environmental management certifications. We maintain full batch traceability from raw glass material through finished products to guarantee consistent quality for every wholesale shipment.
