PP woven sacks score over jute bags for bulk packaging needs
PP woven bags have emerged as the preferred choice for bulk packaging instead of the traditional jute bags. These are widely used packaging material for bulk commodities such as cement, fertilizer, chemicals, food grains and sugar. The benefits of functional performance and savings in cost explain why PP woven bags are in huge demand these days.

Performance parameters

Seepage is very high in jute bags whereas it is low in PP woven bags. There is no possibility of moisture prevention in jute bags but PP woven bags are excellent for prevention of moisture. Contamination or infestation risk is very high in case of jute bags but PP woven bags keep it low or moderate. The organoleptic deterioration is very high in jute bags and minimum in case of PP woven bags. The aesthetic appeal is missing in jute bags but PP woven bags look good. The availability of jute bags is seasonal whereas PP woven bags are easily available throughout the year. Jute bags cost high but PP woven bags are economical to produce. Operational convenience is good for both but jute bags are abrasive. Jute bags deliver fair performance in drop test but PP woven bags are good. There is a high possibility of a microbial attack in jute bags but in the case of PP woven bags, there is no such possibility. Air-borne pollution is high in jute bags but it is zero in PP woven bags. Energy recovery is low in jute bags but high in PP woven bags.

Improved printing effect of PP woven sacks

The objective of packaging is to protect the content and keep it in an ideal form for sales. The appearance of a product is important for marketing initiatives. Since packaging impacts on the success or failure of a product, protection, attraction, promotion, and differentiation call for attention. Product packaging catches a consumer’s roving eye. Based on the packaging strength, they make a decision to choose your product. Attraction from printing effect is important for packaging because the material used, colours, and designs affect the consumer. BOPP printed PP woven sacks make the appearance vivid like a photograph.

Woven polypropylene bags are extensively adopted by the agricultural and manufacturing industries. These are used to keep animal feed, sand, produce, grain, minerals, chemicals, fertilizers, cement, coffee, sugar, flour, and rice. The bags are custom printed with a logo and text on one or two sides and are available in various sizes. They are customized with anti-slip coatings, laminations, and treated to be UV-resistant.

PP Woven Sacks for food grain and sugar packaging

Packaging and storage of food grains and sugar is a challenging task. Both are hygroscopic and thermally active. Ideal packaging solution should have proper mechanical properties to sustain the quality during long-term storage. PP Woven Sacks restrict moisture permeation and insect penetration. The lower temperature during storage ensures lesser insect germination. Better insecticide persistency reduces its application and cost. The odour of the stored commodity is not altered. PP Woven Sacks are superior in the aspect of entomology. Raw materials used for PP Woven Sacks carry safety for food contact applications. These bags conform to food adulteration rules and meet the physico-chemical and biological tests required for food grain storage. Mechanical properties of PP Woven Sacks – tensile strength and stretchability – are superior. Drop impact strength and slip tendencies of bags stacked are better.

PP Woven Sacks for Bulk Tea Packaging

Auction tea is packed in jute, paper or PP Woven Sacks. With changing packaging requirement, better protection of the tea and the viability of packaging cost reduction are to be weighed. The required parameters of tea packaging are evaluated including the mechanical properties of the bags, organoleptic properties of liquor and leaf, chemical quality of the tea.

PP Woven Sacks as the most suitable material for packaging of auction tea. Shelf life evaluation on moisture content and organoleptic properties of tea stored in PP Woven Sacks found to be better than in jute bags. Chemical quality of tea stored in jute and PP Woven Sacks are comparable. Mechanical properties of PP Woven Sacks have been found to be better than jute bags. Transport worthiness and stackability are comparable to that of jute bags. PP Woven Sacks are better and much cheaper for bulk auction tea packaging.

Manufacturers of fertilizers and cement prefer PP Woven sacks over jute bags primarily because they are cheaper in cost, offer better packaging properties, better appeal, higher resistance towards moisture and insects, lower material seepage and pilferage, and lower cost of transportation.

Bulk packaging must be strong, durable, light in weight, provide adequate protection with increased storage and shelf life, easily handled, cost-effective, reusable, and recyclable and the impact on the environment should be minimum. Hence PP woven sacks are ideal for bulk packaging.
