HM Liner Bags
Heavy-Duty Polyethylene Liners
Dhanshri Polypack specializes in manufacturing high-quality HM liner bags that provide strength, durability, and chemical resistance for heavy-duty packaging applications.
Introduction to HM Liner Bags
HM liner bags refer to polyethylene liners made from HM (High Molecular Weight/High-Density Polyethylene) resin. HM offers the following key properties:
- High tensile and puncture strength
- Excellent chemical and abrasion resistance
- Low permeability to moisture and gases
- Withstands rough handling and heavy loads
- Durable and long-lasting performance
These characteristics make HM an ideal material for manufacturing heavy-duty liner bags able to withstand tough conditions.
Types of HM Liner Bags
We offer HM liners in various styles:
- Plain HM liners for general use
- Printed HM liners with branding and product information
- Zipper HM bags with re-closable zipper closures
- Perforated HM liners for breathability
- HM liners with anti-static additives
- Custom HM liner sizes and dimensions
HM liners are available in thickness from 100 microns to 300 microns.
Applications of HM Liner Bags
HM liner bags are commonly used for:
- Packaging industrial raw materials and parts
- Storing and transporting minerals and construction chemicals
- Containing agricultural products like grains and fertilizers
- Heavy tools, metal parts, and hardware items
- Shipping of intermediate bulk containers (IBCs)
HM liners provide secure containment even with rough handling.
Benefits of HM Liners
HM polyethylene liners offer several benefits that make them ideal for heavy-duty packaging:
- High durability – Withstand repeated use and abuse during shipping and handling without tearing or puncturing.
- Puncture and tear resistance – Multi-layered construction provides excellent protection against cuts, nicks, and damage.
- Abrasion resistance – Smooth PE surface prevents abrasion damage from rough packaged contents.
- Chemical resistance – Provides a protective barrier against chemical corrosion and reaction.
- Moisture resistance – Prevents moisture ingress leading to product spoilage or caking.
- Heavy load capacity – Sturdy construction sustains the weight of heavy parts, tools, or minerals without failure.
- Reusability – Can be used multiple times if undamaged, saving costs.
- Customization – Available in different dimensions to perfectly fit containers and boxes.
HM Liner Fabrication
HM liners can be fabricated with additional features:
- Zipper closures – Allow re-sealing liners after opening.
- Carry handles – Facilitate easy handling and portability.
- Perforations – For ventilation and breathability.
- Printing – Product details, safety instructions, branding, etc.
- Co-extrusion – Additional EVOH or PA layers for the enhanced barrier.
- Anti-static additives – For static-sensitive products.
This allows further enhancing liner performance as per application needs.
LDPE vs HM Liners
LDPE and HM liners differ in:
- LDPE is more flexible while HM has higher strength.
- HM provides greater chemical and temperature resistance.
- LDPE allows easier heat sealing. HM requires hotter temperatures.
- HM offers better tear and abrasion resistance.
- LDPE is lower in cost compared to HM liners.
- LDPE is preferable for lightweight goods, HM for heavy-duty use.
HM vs HDPE Liners
HM and HDPE are two types of polyethylene used for liners:
- HM provides higher tensile strength and puncture resistance.
- HDPE offers greater flexibility and elasticity.
- HM has better chemical and abrasion resistance.
- HDPE is more transparent compared to opaque HM.
- HM suits heavy-duty industrial packaging. HDPE suits consumer goods.
- HM is more expensive than HDPE due to its higher performance.
