Description

What are BOPP bags?

The BOPP (Biaxially-Oriented polypropylene Bags) are thermoplastic polymer packaging bags that combine a strong woven polypropylene core with a BOPP film lining of high clarity and gloss. The "biaxially-oriented" film substrate is a plastic that has been stretched in two directions during processing. This improves the plastic's transparency, tensile strength, puncture resistance and low moisture absorption.

When a lightweight durable material is required for packaging and retail distribution, these bags are used. They are also of good aesthetic quality and resist chemicals. These bags are suitable for humid areas, grease, alkalis and acids. These bags suit the packing of household grains, livestock feed, chemical liner uses, and retail needs. BOPP bags are better than many standard plastics in terms of heat resistance, moisture protection, and graphic printability. They can be used for indoor commercial displays and outdoor heavy-duty distribution.

Available BOPP Bag Types

Virgin Food-Grade Bopp Bags

Produced with 100% virgin polypropylene and high-clarity film for superior strength, consistency and chemical purity. Meets strict food safety standards.

BOPP Bags Reprocessed

Bags made from a blend of recycled polyolefins that are cost-effective and suitable for industrial non-critical items, chemical wastes, and rubble transportation.

UV Stabilized BOPP Sacks

The shelf life of the packaging is significantly increased when used for items that are exposed to direct sunlight or outdoor shipping yards.

BOPP Bags in Matte & Colored Finish

Available in a variety of tint bases with elegant matte finishes for product differentiation and brand aesthetic preferences.

BOPP bags with textured and gusseted surfaces

Increased block dimensions, improved structural grip and anti-skid protection for neat vertical stacking.

BOPP Bag Manufacturing Process

Singhal Industries Private Limited manufactures premium BOPP laminated bags under strict quality control using advanced co-extrusion infrastructure and printing.

• Step 1: Selection of the raw materials: High grade virgin Polypropylene Resin and premium BOPP Films are used to provide uniformity of tensile measurements and excellent printability.
• Step 2 - Gravure Printing: The raw BOPP films are run through a high speed rotogravure machine whereby the custom brand colors are reverse printed onto the film.
• Step 3: Extrusion weaving and lamination: The printed film will be laminated to the fabric by the hot extrusion melt technique, tubes are continuously made by the tape to be woven by the process of extrusion.
• Step 4: Cooling and calibration: Multi-layer fabric is stabilized by applying a controlled roller pressure and cooling in order to maintain the integrity of the surface.
• Step 5: Quality Testing: The thickness accuracy test is carried out in a rigorous manner in each batch of production.
• Step 6 - Fabrication & Dispatch: Sacks will be slit or cut and then back-seamed, bottom stitched and packaged safely to prevent damage in transit.

FAQs (Frequently Asked Questions)

Q1: What is the purpose of BOPP bags?

The bags can be used for packaging consumer chemicals, agricultural grains, storage of fabrication components, construction bags made from white cement, and retail food.

Q2: Can BOPP bags be heated?

The bags are structurally stable when filled with warm products. They have a good heat resistance, as compared to other plastics.

Q3: Can BOPP bags be used in a chemical-resistant environment?

Our BOPP laminated bag offers excellent resistance to acids and alkalis as well as processing oils and many industrial chemicals.

Q4: Can BOPP Bags Be Cleanly Sewn or Welded?

You can stitch BOPP bags using industrial-grade sewing threads, or use hot melt adhesives to backseam them for automated line integration.

Q5: Can BOPP bags be used in the rain?

The outer laminated film blocks the water vapor from reaching woven cores.

Q6: What is the difference in BOPP bags and HDPE standard bags?

HDPE bags have high tensile strength and are more durable and resistant to any kind of impact and cold.

Q7: Can Custom BOPP Bags be provided?

Bagging can be done according to corporate standards, and includes bag height, gusset width, film color index, and printing.

Q8: Are BOPP bags recyclable?

The polypropylene polymer base is 100% recyclable and can be reprocessed to produce other secondary plastic utility products.

Q9: Which industries use BOPP bags?

Chemical processing, consumer packaging, premium agriculture and building construction industries, as well as industrial fabrication, choose BOPP bags in large numbers.

Q10: What is the thickness of BOPP Bags?

The thickness parameters you need will depend on the weight of your product, its transit handling, exposure to chemicals, and the vertical stack height.

Q11: Can moisture affect the layout or print of BOPP Bags

No. Water, grease or mud will not damage or rub off the brand images because they are printed on the reverse of the scratch-resistant film layer.

Q12: Can reprocessed bags be used for retail grains?

Not at all. Virgin Polymer bags are ideal for food and agricultural crops packaging whereas the reprocessed bags are excellent for industrial minerals, waste collection and demolition debris.

Q13: Would these bags be able to hold very fine chemical powders without any sifting through?

Yes. The solid extrusion film closes off the spaces in between the woven tapes. Therefore, the bags become sift proof and will prevent fine chemical powders from sifting through the needle hole.

Q14: How would the lightweight bags help in budgeting within the corporation?

These high strength bags have a polymer density of about 0.90g/cm3. Thus, they hardly add any weight to the bulk cargo. Consequently, this will help in cutting down the deadweight transportation cost.

Q15: How do we go about getting a wholesale factory quotation for the corporate?

The B2B procurement managers can reach out to the central export desk. They can do so by giving us target bag dimensions, weight restriction preferences, graphics for printing as well as destinations ports.
