High-Pressure Transparent Heat-Seal PE Sealing Bags – Product Description
Product Overview
Our High-Pressure Transparent Heat-Seal PE Sealing Bags are manufactured from premium low-density polyethylene (LDPE) resin through a high-pressure polymerization process. The material is odorless, tasteless, and non-toxic, complying with food-grade packaging hygiene standards-. These bags offer exceptional transparency, flexibility, and heat-sealability, making them an ideal choice for a wide range of packaging applications across food, daily chemical, industrial, and retail sectors.
Key Features
-
High Transparency & Gloss – The low crystallinity (45–65%) of LDPE gives these bags excellent clarity and gloss, allowing your products to be clearly visible and enhancing shelf appeal.
-
Superior Heat Sealability – With a low initiation sealing temperature of 90–110°C and high heat-seal strength, these bags form a strong, airtight seal quickly whether using manual or automatic heat-sealing equipment. The seal effectively blocks air, moisture, and contaminants, preventing oxidation, dampness, and spoilage.
-
Excellent Flexibility & Puncture Resistance – The highly branched molecular structure of LDPE provides outstanding flexibility, high elongation, and impact resistance. The bags are soft to the touch, produce little noise when rubbed, and resist tearing under normal handling.
-
Good Low-Temperature Resistance – These bags perform reliably in cold environments, withstanding temperatures as low as –60°C without becoming brittle or cracking – ideal for frozen food storage.
-
Moisture-Proof & Chemical Stability – The material provides effective moisture resistance, oxygen barrier, and resistance to acids and alkalis. It is chemically stable and does not react with contents, ensuring safe packaging for food, pharmaceuticals, and other sensitive products.
