LDPE vs HDPE Liner Bags – Which One to Use?
| Feature | LDPE (Low Density) | HDPE (High Density) |
|---|
| Flexibility | High – soft and stretchy | Low – rigid and stiff |
| Transparency | High – clear and transparent | Lower – hazy or opaque |
| Tear Resistance | Good – stretches before tearing | Higher tensile strength |
| Heat Resistance | Lower (~115°C melting point) | Higher (~135°C melting point) |
| Chemical Resistance | Good | Better |
| Best For | General lining, food grade, soft goods | Heavy chemicals, high temp applications |
| Cost | Lower | Higher |
Recommendation: For most PP woven bag applications including rice, fertilizer, cement and food grain packaging, LDPE liner bags are the most cost effective and practical choice. Choose HDPE only for heavy duty chemical or high temperature applications.
Frequently Asked Questions
What is an LDPE liner bag?
An LDPE liner bag is a flexible, transparent inner bag made from Low Density Polyethylene. It is placed inside PP woven sacks, drums or cartons to provide moisture proof, dust proof and leak proof protection for the packed product.
What is the difference between LDPE and HDPE liner bags?
LDPE liner bags are more flexible, soft and transparent compared to HDPE. LDPE stretches around sharp objects instead of tearing. HDPE is more rigid and has higher tensile strength. LDPE is preferred for general purpose lining while HDPE is used for heavy duty chemical storage.
What thickness of LD liner bag should I use?
For light products like food grains and powder use 30 to 50 micron. For standard industrial use like fertilizer and chemicals use 50 to 100 micron. For heavy duty applications with sharp edged products use 100 to 200 micron thickness.
Do you supply food grade LDPE bags?
Yes. We manufacture food grade LDPE liner bags using 100% virgin LDPE material that is safe for direct food contact packaging of rice, flour, sugar, spices and food grains.
Can LDPE liner bags be used inside PP woven bags?
Yes. LDPE liners are specifically designed to be inserted inside PP woven sacks to provide an additional moisture barrier, prevent leakage of fine powders and protect the product during storage and transportation.
What is a natural inner bag?
A natural inner bag refers to an LDPE liner in its natural unpigmented color which appears translucent or milky clear. Natural inner bags are the most cost effective option and allow easy visual inspection of contents.
What sizes of LDPE liner bags are available?
We manufacture LDPE liner bags in fully custom sizes as per your PP woven bag or container dimensions. Simply share the width, length and required micron thickness and we will manufacture to your exact specifications.
What is a reprocess (RP) liner bag?
A reprocess or RP liner bag is made from recycled LDPE material. It has a semi natural or slightly dull appearance compared to virgin LDPE. RP liners are the most economical option and are suitable for non-food industrial applications like fertilizer, cement and chemical packaging where food grade certification is not required.
What is a milky liner bag and why is it used for sugar bags?
A milky liner bag is a special LDPE liner with a milky white opaque appearance. It is specifically designed for sugar bag packaging because it hides the product from direct view providing a clean uniform appearance and offers excellent moisture barrier to protect hygroscopic products like sugar from absorbing humidity.
What is the difference between natural, milky and reprocess (RP) liner bags?
100% Natural liners are made from virgin LDPE and are fully transparent and food grade safe for rice, flour, sugar and food products. Milky liners have a white opaque finish specifically designed for sugar and premium product packaging. Reprocess RP liners are made from recycled LDPE, have a semi natural dull appearance, are the most affordable, and are suitable for non-food industrial use like fertilizer and cement.
What is the minimum order quantity for LD liner bags?
Minimum order quantity depends on size, micron thickness and variant type. Please contact us on WhatsApp at +91 8320525550 for exact MOQ and best pricing for your requirement.
