Hand Stretch Wrapping Machine

 

Introduction

The Hand Stretch Wrapping Machine is a machine for packaging items. It's usually done manually, using stretch film to wrap items and secure them together for shipping and storage. Secondly, we use the squeeze casting method to operate. The maximum winding width of the product is 500mmX3, and we also have a mechanical size of 12mX3.5mX2.5m. Finally, the maximum linear speed of our products is 120m/min, and the maximum extrusion thickness is 0.05mm.

 

Feature

Simple and easy to use
The Hand Stretch Wrapping Machine is a very simple and easy to use film applicator. It requires only one person to apply the film and does not require any professional training or skills.

 

Cut costs
Since only one person is required to use the machine, costs can be saved and material loss can be greatly reduced in long-term use.

Wide applicability
Our products can be used in all types and sizes of product packaging, from small boxes to large sheets.

 

Reliable and durable
Our products are designed to be versatile and durable for long-term use, easy to maintain and maintain, reliable and long-lasting.

 

 

 

This equipment is primarily employed in the manufacture of wrapping film that is utilized for the centralized packaging of a wide array of products, as well as for multi-layer wrapping packaging of stacked goods on pallets. Its waterproofing capabilities make it highly useful in the express logistics packaging industry.
