Clarification of poly bag

Details Clarification of poly bag.

Normally we used various kinds of bag to pack the goods. Poly bag is the most common and important item of them. Normally we bought various kinds / type of poly bag from the market. Most of the product is packed with poly bag.

Mainly in the apparel sector poly bag is a very common item. We packed the garments with the poly bag before insert in a carton for shipment. Sometimes we use one poly for one garment, we called it single poly. Sometimes we insert several single poly in a big poly we called it “blister poly”.

Considering the material there is several classifications in these Poly. Please find below the main classifications poly with all the details.

PE (Polyethylene) :

A lightweight thermoplastic used especially in packaging.  It is tough, flexible and chemical resistance characteristics.

PP (Polypropylene):

Polypropylene has excellent chemical resistance is strong and has the lowest density of the plastics used in packaging. It is stiffer and clearer than polyethylene and has excellent resistance to water, salt and acid solutions and, when manufactured with virgin resin, polypropylene (PP) meets FDA requirements for food applications. Polypropylene (PP) is exceptionally suited to maximize the visual appeal of food and display products. Any Product that needs an outstanding professional appearance can benefit from polypropylene (PP) packaging.

LDPE = Low Density Polyethylene:

Low Density Polyethylene is the most commonly used material for flexible packaging because it is tough, transparent and electrically stable. Low Density Polyethylene (LDPE) also has a low melting point, which is required for heat sealing applications. When low density polyethylene bags (LDPE) are made with virgin (no additives) polyethylene resin, they meet FDA standards for use with food products.

LLDPE = Linear Low Density Polyethylene:

A given thickness of Linear Low Density Polyethylene (LLDPE) is significantly stronger than the same thickness of Low Density Polyethylene (LDPE). Therefore, Linear Low Density Polyethylene (LLDPE) can be thinner and lighter and perform the same job as LDPE. These bags are bottom sealed for added strength. Linear Low Density Polyethylene (LLDPE) also has a low melting point, which is required for heat sealing applications.

HDPE = High Density Polyethylene:

High Density Polyethylene is used because of its excellent strength and significantly lighter weight. It has excellent protection capability and it is used in grocery and other retail segments extensively, while also suitable for a myriad of other uses.

Nylon Laminated Polyethylene

Nylon Laminated Polyethylene Vacuum packaging is the process of removing the air from within an impermeable plastic package and sealing food items inside to maintain flavor, freshness and color. Some forms of harmful bacteria thrive in the presence of oxygen. A Nylon film is incorporated into vacuum bags to prevent oxygen from returning to the bag after the extraction process, and prevents bacteria from spoiling the contents. Nylon vacuum bags can be used to preserve many different types of food, including beef, lamb, chicken, fish and cheese.
