PE coated paper, also known as polyethylene-coated paper, is a type of paper that has a layer of polyethylene (PE) applied to its surface. This coating enhances the paper's properties, making it highly resistant to water, oil, and other liquids, making it ideal for a wide range of packaging applications.

The production process of PE coated paper involves a method known as extrusion coating, where molten polyethylene is applied to the surface of the paper. This process creates a smooth, uniform layer of PE that bonds tightly with the paper fibers. The paper is then cooled and dried to set the coating in place, giving the paper its enhanced properties.

PE coated paper is widely used in industries such as food packaging, where moisture and oil resistance are crucial. It is commonly found in products like fast-food wrappers, beverage cups, take-out containers, and food trays. Its durability and strength make it suitable for holding hot and cold foods, while the PE coating ensures that the paper does not weaken or degrade in wet conditions.

Dongsenpaper, a leading brand in the industry, specializes in high-quality PE coated paper. Known for its superior coating technology and consistent product performance, Dongsenpaper offers a range of PE coated papers tailored to meet the needs of various industries. Whether for food packaging or retail applications, Dongsenpaper provides reliable and durable solutions that help businesses enhance their product presentation and functionality.

With its excellent waterproofing and oil-proof capabilities, PE coated paper from Dongsenpaper is a trusted choice for businesses seeking a versatile and effective packaging material.

If you’re in the packaging business, you’ve probably come across PE coated paper—but what exactly makes it different from other coated papers?



PE coated paper is regular paper with a thin layer of polyethylene (PE) added to one or both sides. That layer makes the paper waterproof, grease-resistant, and heat-sealable. In other words, it holds up well when used for things like hot drink cups, food containers, or even medical packaging. It doesn’t soak through, it doesn’t tear easily, and it can be sealed shut to keep products fresh.



Compare that with other coated papers like art paper or clay-coated paper. Those are mainly made for nice printing—think brochures, posters, or packaging labels. They may look great, but they aren’t built to handle moisture or heat. Drop a bit of oil or water on them, and they’ll wrinkle or leak.



At dongsenpaper, we focus on making high-quality PE coated paper that’s safe, strong, and ready for real-world use. Whether you need it for takeaway boxes, trays, or custom food packaging, we’ve got options to fit your needs.Get best PE coated paper from us quickly.

Origins and Core Requirements of High Altitude Butane Gas Canister

Driven by User Pain Points

• Mountaineering Accident Case: 2023 frostbite incident in the Alps caused by gas canister leakage

• Standard canisters exhibit 37% flame output reduction above 2,500m altitude (data sourced from Journal of Outdoor Equipment)

Industrial Response

• 1992: Coleman pioneers "Altitude-Tuned Canister" concept

• Modern alpine canister benchmarks:

Pressure resistance ≥3.8MPa

Operational temperature -30°C to 50°C

EN417 certification compliance

High Altitude Butane Gas Canister

Net Weight	Size
110g	90x70mm
230g	110x90mm
450g	110x145mm

Structural Differences: Two-Piece Butane Gas Canister vs. Three-Piece Butane Gas Canister

Product Name	Two-Piece High Altitude Butane Gas Canister	Three-Piece Butane Gas Canister
Reference Picture
Can Structure	Seamless can body + base (no side welding)	Welded can body, top, and base
Production Process	Deep-drawn forming, better sealing	Multiple weld seams, higher leakage risk
Pressure Resistance	typically ≥3.8MPa	typically ≤2.5MPa
Cold Resistance	Works reliably at -30°C	May underperform below 0°C
High-Altitude Use	Optimized for 3000m+ elevation	Best for low-altitude conditions
Cost	Higher (premium materials & process)	Lower (mass-market production)

Advantages of Two-Piece High Altitude Butane Gas Canister

No welds, safer: Fewer leakage points, ideal for high-pressure environments.

Better cold resistance: Seamless design avoids brittleness in low temperatures.

Why Are Two-Piece Butane Gas Canister Valves More Reliable?

Leak-proof design: Dual sealing ensures safety even if O-rings degrade.

Cold-optimized: Special valve materials prevent freezing or jamming.

Stable gas output: Maintains consistent flame in low-oxygen environments.

Why Are Two-Piece Butane Gas Canister Better for High Altitudes?

(1) Optimized Fuel Blend

Alpine canisters use isobutane + propane mix (e.g., 70/30 ratio), while standard cartridges often use pure butane.

Higher propane = better cold performance (propane boils at -42°C vs. butane at -0.5°C).

Stable vaporization at low pressure, preventing weak flame output.

(2) Higher Pressure Resistance

Alpine canisters typically have a 3.8MPa burst pressure, vs. ~2.5MPa for standard cartridges.

Withstands extreme temperature swings in alpine environments.

(3) Lightweight & Portable

Made from high-strength nickel-plated steel, alpine canisters are lighter yet stronger than standard cartridges.

Industry Standards & Buying Guide

✅ How to Identify a High-Quality Alpine Canister?

• Check certifications: EN417 (Europe), DOT (USA).
• Inspect the valve: Metal-threaded valves (plastic valves indicate lower quality).
• Weigh it: A 450g alpine canister should weigh 160-170g when empty (lighter may mean inferior materials).

🚫 Common Misconceptions

• Standard cartridges work fine for mountaineering” → May fail in cold or high-altitude conditions.
• Alpine canisters can be refilled” → Never! Non-refillable by design—extremely dangerous to tamper with.

Which One Should You Choose?

Scenario	Recommended Choice	Reason
Low-altitude camping	Standard gas cartridge	Cost-effective, sufficient performance
High-altitude climbing	High Altitude Butane Gas Canister	Cold-resistant, high-pressure stable flame
Extreme conditions	High Altitude Butane Gas Canister (high propane %)	Ensures operation below -30°C
