      Consumers are confused about the safety of chemicals in plastic. Even federal government agencies don't agree about the hazards posed by bisphenol-A, or BPA, an estrogen-like chemical used in plastic. structures that fit the requirements of a specific food or beverage can help for answering previous questions. The theory and model to be presented are applied to coextruded, extrusion coated or laminated plastic films. Following factors are strongly considered: • Food or beverage environmental or storage conditions • Package characteristics. The magnitude and extent of seepage loss relative to the canal size affects the economics of lining feasibility. For example, if 20% of the water from a cfs canal is lost in a 1/4 mile section out of 20 miles of canal then a decision to line may be .

Levering on our immense professional experience in manufacturing and supplying sectors, we are engaged in providing the superior quality LDPE Canal Lining Film. Offered film finds its best application in reservoirs, pond lining, ore processing plants, road lining etc.

This film is carefully manufactured with the utilization of supreme quality low density polyethylene and pioneered. Some of the primary ones are: Polyethylene – The most common plastic film is made of one of the varieties of polyethylene: low-density polyethylene, medium-density polyethylene, high-density polyethylene, or linear low-density polyethylene.

Polypropylene – Polypropylene can be made a cast film, biaxially oriented film (BOPP). Another simple method of canal lining with soils entails applying a layer of compacted silt on top of the subgrade of the canal. The use of soils as canal linings is efficient for controlling seepage, but not effective against weed growth.

Plastic membrane. Plastic linings are often referred to as geomembranes or flexible membrane linings. Plastic linings are often covered with soil.
