50L–5000L Rotational Molded Industrial Round Plastic Containers With Tapered Design

50L–5000L LLDPE Rotational Molded Industrial Round Tub with Tapered Design for Food Processing 

Product Overview

This industrial round tub is manufactured from LLDPE using a rotational molding process, forming a seamless one-piece structure without welding joints. The uniform wall thickness improves structural stability and reduces deformation risk during repeated use.

The tapered cylindrical design allows efficient stacking and nesting, helping reduce storage space and transportation cost. With a capacity range from 50L to 5000L, the product can be used in various industrial, agricultural and food processing scenarios.

LLDPE material provides stable performance under wet and general industrial environments, with good resistance to impact and moisture. The smooth inner surface helps reduce residue and supports easy cleaning.

Cause

In industrial handling and food processing applications, containers are often exposed to repeated loading, stacking and cleaning cycles. Traditional injection molded or welded containers may have uneven wall thickness or structural weak points.

These issues can lead to deformation, cracking or reduced service life, especially under liquid load or long-term stacking conditions.

Solution

Rotational molding technology forms the container through uniform heating and rotation, allowing LLDPE material to distribute evenly along the mold surface. This process eliminates weld seams and ensures consistent wall thickness.

The one-piece structure improves load distribution and reduces stress concentration. The tapered design further enhances stackability, making storage and transportation more efficient.

Specifications

Application

Food processing and fermentation containers
Aquaculture water and feed storage
Agricultural material handling
Warehouse storage and transport
General liquid and bulk material storage

How It Works

Rotational molding works by placing LLDPE powder inside a mold, which is then heated and rotated along two axes. The material gradually melts and coats the inner surface of the mold evenly.

This process forms a hollow container with consistent wall thickness and no welding seams. After cooling, the final product is removed from the mold with stable structure and dimensional consistency.

How To Choose

Choose capacity based on handling volume requirements
Confirm height according to storage or transport limitations
Select tapered models for stacking and space saving
Ensure food-grade material for food processing applications
For liquid storage, consider stability based on diameter and height ratio
