Poly Bag Manufacturing Process

MANUFACTURING DESIGNS

BOTTOM SEAL: These bags are cut individually from seamless tubing and are sealed at the bottom of both flat and gusset bags. This is the strongest seal available and is suggested for bags with heavy-duty uses.

SIDE SEAL (SIDE WELD): These bags are made from folded polyethylene sheeting, sealed on each side. This seal (or weld) can be used on at and gusset bags and is suggested for retail uses.

BAGS ON PERFORATED ROLLS: These bags are made on a continuous roll of seamless tubing perforated at specified intervals for ease in tearing the bag off the roll. The “top” opening can be above or below the perforation. This storage configuration takes minimum storage space and is routinely used for bin liners, pallet covers and very long bags. Pre-opened bags are suitable for automated bag-filling machines.

BACK SEAL: For these bags, polyethylene sheeting is folded and sealed along the backside of the bag to form a tube. The bags are cut and bottom-sealed and are the required type of bag for wrap-around printing.

HEADER PACK: These are side welded bags with a perforated top lip stapled to a header card. They are used with semi-automatic bag opening machinery or in manual operations. They are packed with 100 bags per header card.

FLAT SHEETING: Sheeting is used for wrapping, lining and dividing layer.

WICKET BAG: These are side-welded bags with two holes in the lip fi> to a metal wicket. They are used with automatic and semi-automatic I openers or in manual operations.

RECLOSABLE BAGS: Seal Top reclosable bags can be made with or without

a tamper evident seal. The use of these bags is preferred when there is the need for multiple entries or repackaging of the bag.

HEADER BAGS: These bags are side-welded with a continuous sea along the top width, 2"-3" below the fold. The bags are loaded and sealed from the bottom. Reinforced headers are available.

FLIP-TOP BAG: These are side-welded bags with a fold over lip.

POCKET BAG: These bags are sealed in separate pockets along their length for the purpose of multiple unit packaging within a single bag

DOOR KNOB BAG: These are side-welded, staple packed bags with a perforated lip and hole just below the top of the bag.

Types of Polyethylene Bags

POLYETHYLENE BAGS:

These are the most common plastic bags. The polyethylene bags we stock are made from virgin materials, so they comply with FDA requirements for use in food applications. A wide selection of sizes and gauges are available to meet virtually any need you might have.

Available in the following bag styles:

• Lay Flat
• Seal Top
• Covers & Tarps
• Utility Bags on Rolls
• Drawstring
• Gusseted Poly Bags
• Trash Bags
• Tubing
• Mattress Bags

HIGH DENSITY:

High molecular weight, high density film makes these bags strong and durable. Ideal for shopping bags. Several of these bags are packaged in a low cube dispenser carton that is easy to use at the retail counter and stores easily on shelves. Meet FDA requirements for food use.

Available in the following bag styles:

• Merchandise Bags
• Utility Bags on Rolls
• T-Shirt Bags

POLYPROPYLENE BAGS:

Polypropylene bags have long been the premier choice for outstanding product presentation and to preserve freshness. Excellent clarity, vapor and moisture barrier properties. Meet FDA requirements for food use.

Available in the following bag styles:

• Flat
• Gusseted
• Seal Top
• Drawstring

STATIC CONTROL BAGS

PINK ANTI-STATIC: Pink Anti-Static bags are an excellent choice when static control is necessary, but Faraday Cage Protection is NOT required. They effectively eliminate the hazard of static damage to sensitive electronic components during packaging, storage and shipping.

Available in the following bag styles:

Flat • Seal Top • Tubing

POLYETHYLENE GUSSET BAGS

LLDPE (Linear Low Density Polyethylene) bags provide extra strength and impact resistance that allows a lighter gouge bog to do the same job as a heavier gouge LDPE bag LOPE (Low Density Polyethylene) provides excellent protection for everyday use at a great price

• Mode from seamless tubing and ore bottom sealed for extra strength, with no slits or side seal
• Bogs 15" wide and under come in dispenser pocks of l 00 for cleanliness and convenience
• Meet FDA requirements for use in food applications
• Any size not listed can be custom made to your specifications

POLYETHYLENE FLAT BAGS

LLDPE (Linear Low Density Polyethylene) bags provide extra strength and impact resistance that allows a lighter gauge bag to do the same job as a heavier gauge LOPE bag. LDPE (Low Density Polyethylene) provides excellent protection for everyday use at a great price

• Made from seamless tubing and are bottom sealed for extra strength, with no slits or side seals
• Meet FDA requirements for use in food applications

Poly Bag Dimensions

The first dimension stated when describing a poly bag is the width. All bag measurements are inside diameter (ID).

Types of Materials & Additives

LOW DENSITY

• Virgin low density polyethylene complies with FDA and USDA requirements for use with food.
• Fractional Melt improves strength in cold temperatures.

LINEAR LOW DENSITY POLYETHYLENE

Stronger than low density polyethylene and puncture resistant. Complies with FDA and USDA requirements for use with food.

Pink Anti-Static Tubing

• Pink Anti-Static Tubing is an excellent choice when static control is necessary but Faraday Cage Protection is NOT required
• Amine free
• Excellent for packaging products of varying lengths
• All sizes supplied on 12" diameter rolls

HIGH DENSITY POLYETHYLENE

For use in retail and industrial applications.

POLYPROPYLENE

Preserves freshness with vapor and moisture barriers. Excellent clarity for product presentation.

STATIC SHIELDING

Buried metal construction provides Faraday Cage protection.

ADDITIVES

• Metalocine: Adds strength and flexibility. High thermal stability.
• EVA: Adds strength and improves seal ability. For use in cold

temperatures to prevent breakage of the bag.

• Slip: Reduces slippage when bags are stacked. Used in mattress bags, etc.
• Anti-Static: Protects static sensitive products. Amine-free or regular.
• Ultraviolet Inhibitor (UVI): Prolongs the life of the bag

when exposed to sunlight. Used in pallet covers, tarps, etc.
