Bubble bag definition:
Bubble bag refers to the packaging bag made of bubble film.
Also known as Air cushion Film, Air Bubble Film, Bubble cloth, Bubble paper, Bubble Film, Bubble Film, Air cushion Film.
Bubble film, is a high-pressure polyethylene as the main raw material, and then add whitening agent, opening agent and other auxiliary materials, after about 230 degrees high temperature extrusion blister products.
It is a kind of chemical product for packing and filling.
With good shock absorption, impact resistance, thermal bonding, non - toxic, tasteless, moisture proof, corrosion resistance, transparency and other advantages.
Bubble film is made of low density polyethylene, which is a kind of transparent flexible packaging material widely used at present.
The principle is that the film contains air to form bubbles to prevent product impact, to ensure that the product is protected by vibration, but also has the role of heat insulation, suitable for different products in all walks of life packaging or turnover!

What is the difference between PE film and PET film
For Polyethylene PE, full name, is the most simple structure of high polymer organic compound, the world's most widely used polymer materials.
PE protective film is based on special polyethylene (PE) plastic film, which can be divided into high density polyethylene protective film, medium density polyethylene and low density polyethylene according to the density.
The biggest advantage of PE protective film is that the protected product is free from pollution, corrosion and scratch in the process of production, transportation, storage and use, so as to protect the original bright and clean surface, thus improving the product quality and market competitiveness.
PET film is also known as film high temperature resistant polyester film.
It has excellent physical properties, chemical properties and dimensional stability, transparency, recyclability, can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial film, packaging decoration and other fields.
PET film is a kind of packaging film with comprehensive properties.
Its transparency is good, luster;
Good air tightness and incense retention;
The moisture resistance is moderate and the moisture permeability decreases at low temperature.
The mechanical properties of PET film are excellent, and its strength and toughness are the best among all thermoplastics.
And good stiffness, size stability, suitable for printing, paper bags and other secondary processing.
PET film also has good heat and cold resistance, chemical resistance and oil resistance.
But it is not resistant to strong alkali;
Easy to carry static electricity, there is no appropriate method of anti-static, so in the packaging of powder should be noted.
There are two types of bubble film: single-side bubble bag and double-side bubble bag. Single-side bubble bag is suitable for protecting light weight products, and double-side bubble bag has strong shockproof force and is suitable for packing large and heavy articles.
Single and double bubble bags are suitable for packaging of products in various industries, such as making bags and slicing.
Single and double bubble bags can be equipped with anti-static bubble bags, and different colors of pearl cotton bags, printing.
Bubble film is the principle of the bubble film contains air to form bubbles to prevent product impact, to ensure the protection of products from vibration, but also has the role of heat insulation, suitable for different industries of different products packaging or turnover!
Because the bubble film is filled with air, so the body is light, elastic, with sound insulation, shockproof, anti-wear performance, it is waterproof, moisture-proof, and compressive.
