For these types of applications it's common to use the spout that's fitted to the corner of the pouch as typically these types of products tend to be poured out and then the cap replaced as generally they are multi use packs. For these more robust applications we have developed a special range of nylon based laminate structures that are more abuse resistant than standard materials. Typically packs sizes range from around 300mls to 5 litres but larger pouches are available. Spout sizes are from 8.5mm to 22mm. This style of pouch is very popular for refill applications. Manufactures initially supply their products in a dispensing unit and then sell theses pouches as a refill for the dispenser. The main benefits are environmental, convenience and cost.
Tablished in 1991, the spout pouch supplier-ld pack co ., ltd is located in xiqiao technology & industrial park, nanhai district, foshan, guangdong province. Having more than 400 employees, the factory is equipped with 5 sets of 8 to 12 colors printing and lamination production line which guarantee an annual production capacity of over 12, 000 tons. The production base covers an area of more than 30, 000 square meters and a building area of 50, 000 square meters where the workshops are designed and built according to the international standards to create aenvironmentallyal friendly, clean, healthy and safe environment.
Our company is devoting to flexible packaging mainly for food, beverage, meat, flavoring, snack food, daily household cleaning products as well as chemical goods. It has developed about 30 series of packaging materials with different material structure and packaging purpose including flat bottom pouch, spout pouch, easy-peelable film, high barrier film, zipper bag, vacuum pouch, stand up pouch and lables etc.
Our products are mainly sold to customers in major domestic cities and exported customers from america, europe, australia, new zealand, korea, africa, middle east etc., many of which are well-known domestic and multinational companies.

Ozone decomposition catalysts primarily achieve catalytic reactions by facilitating the breakdown of ozone molecules into oxygen atoms and oxygen ions. The mechanism of action of the catalyst involves two main aspects: first, enhancing the adsorption performance of ozone molecules on the catalyst surface, and second, playing an activating role in surface reactions. Currently, common ozone decomposition catalysts include metal oxides, transition metal complexes, and ion exchange resins.

Hopcalite Catalyst is a widely used catalyst for air purification. It is primarily employed to remove toxic gases from the air, especially carbon monoxide (CO) and sulfur dioxide (SO2). Hopcalite Catalyst plays a crucial role in improving air quality, reducing the emissions of harmful gases, and protecting the environment. It is a key component in many air pollution control systems. Composition: Hopcalite Catalyst is typically composed of a mixture of copper and manganese oxides. This specific combination is highly effective in catalyzing certain gas-phase reactions. Principle: The key function of Hopcalite Catalyst is to catalyze gas-phase reactions that convert toxic gases into harmless substances. For example, it can catalyze the conversion of carbon monoxide (CO) to carbon dioxide (CO2) or sulfur dioxide (SO2) to sulfur trioxide (SO3). These reactions transform harmful gases into relatively harmless or more easily manageable compounds.
