How PET Preform Wire Containers Delivered 300% Storage Gains for Nestlé and Coca-Cola

How PET Preform Wire Containers Delivered 300% Storage Gains for Nestlé and Coca‑Cola

In the beverage industry, efficient storage and movement of PET preforms directly affect production uptime and warehouse throughput. HM Group, a manufacturer of industrial wire containers based in Dalian, China, has deployed its PET Preform Wire Container (model HM‑PPC22) and Wire Container With PP Sheet (model HM‑HD028) in two Fortune‑500 supply chains, demonstrating measurable gains in storage density, material handling efficiency, and inventory accuracy.

The Challenge: Inefficient Space Use and Safety Risks in Preform Warehousing

Large‑scale beverage producers, such as Nestlé in Pakistan and Costa Rica and Coca‑Cola in South Africa, rely on high‑volume preform inventories that must transition between injection‑molding and blow‑molding lines. Traditional floor‑level storage consumed large footprints, slowed stock counting, and created safety hazards from bulk‑bag collapses. These bottlenecks limited production throughput and increased operational risk.

Industry Background: PET Preform Handling Demands Rugged, Stackable Containers

PET preforms are lightweight but sensitive to surface scuffing and contamination. The industry requires containers that offer rigid support, high stackability, fork‑truck compatibility, and a non‑abrasive interior. Wire containers with PP sheet linings and precision‑engineered mesh have become the standard solution for this application, because they combine visibility, airflow, and structural integrity.

The Solution: HM Group’s PET Preform Wire Container

HM Group’s PET Preform Wire Container (model HM‑PPC22) is a collapsible, stackable storage unit built from mild steel Q235. Its exterior dimensions are 1196 L × 1008 W × 1174 H mm, with a wire gauge of 4.8–12 mm and a grid size of 62 × 125 mm. It has a loading capacity of 600 kg and can be stacked 5 + 1 high. The container is available with zinc, hot‑dip galvanized, or powder‑coated finish, and can be fitted with a PP sheet inner lining to protect preform surfaces. For applications requiring additional side protection, the Wire Container With PP Sheet (model HM‑HD028, 1200 × 1000 × 1140 mm) offers a 500‑kg capacity with a 50 × 100 mm grid and 4‑high stacking.

Step‑by‑Step Deployment and Results

1. Nestlé – Pakistan & Costa Rica (10,000 units)

• Application: Centralized bulk storage and vertical logistics of PET preforms across large‑scale beverage production hubs.
• Outcome: A 300% increase in warehouse storage capacity through secure 4‑high vertical stacking. Stock counting and identification speed improved by 40%, enabling the turnover of millions of preforms. The project achieved 4‑tier high stacking stability under heavy‑duty loads, with professional‑grade zinc or powder coating for long‑term industrial reliability.

2. Coca‑Cola South Africa (5,000 units)

• Application: Specialized bulk storage and high‑density vertical logistics of PET preforms within the production supply chain.
• Outcome: A 400% increase in warehouse storage density by enabling vertical stacking of 4 to 6 tiers. Internal material handling efficiency rose by 35%. The open‑mesh design allowed 100% instant visual stock checks, reducing inventory counting time by half. Stacking stability was validated at 6 levels under full load, and the precision‑engineered mesh with PP sheet inner lining eliminated preform scuffing.
