How to clean a lunch bag

A clean lunch bag will always ensure you never run into issues such as odor or food poisoning. Follow the steps below to clean your lunch bag effectively.

Step 1: Check the fabric care label

Checking this label will allow you to determine the proper way to clean the bag without damaging the fabric. This label will also tell you whether or not the bag is machine washable.

If your bag is machine washable; use cold water and gentle detergent and wash on a gentle cycle.

For bags that are not machine washable; you will need: warm water, soft cloth, scrub brush, mild soap, or detergent.

Step 2: Pre-treat any stains

Soak the bag for an hour or so in your preferred stain remover. Avoid any stain remover with bleaching properties.

Step 3: Clean gently with a scrub brush

This brush will remove the stubborn stains on the tough material.

Step 4: Wash the bag in detergent

Add some detergent in warm water and use your bare hands to wash the bag.

Step 5: Rinse the bag

Use plenty of clean water to rinse the bag and then hang it to dry in the sun.

How to remove smell from a lunch bag

Use water, detergent, and a cloth to wipe the bag inside and outside. You can add fabric softener to the water to help remove the smell. Don’t forget to wipe all the pockets, straps, and handles. Turn the bag inside out and leave it in the sun to dry. The sun will deodorize the bag and remove any unsavory odors.

How to sew an insulated lunch bag

The best thing about sewing your lunch bag is that it allows you to be creative and customize everything about the bag. The bag we are going to sew features: a hook and loop front closure, a top handle, and an easy to clean vinyl lining. A special insulating batting is inserted between the lining and exterior layers to help keep the contents of the bag at an appropriate temperature. There is an optional shoulder strap that will make it easier for you to carry the bag around.

Step 1: Gather all the materials you require

  1. 18 inches exterior fabric
  2. 18 inches lining fabric
  3. 9 inches of medium weight fusible interfacing
  4. 18 inches Insul bright polyester fabric
  5. Two swivel hooks for the shoulder strap
  6. Two three-quarter inch wide D rings for the shoulder strap
  7. One two and a quarter inch long strip of three-quarter inch wide hook and loop tape

Step 2: Cut the fabric

  • Exterior fabric, lining fabric Insulation and vinyl fuse
  • One piece 28 inches by 8 inches (for the body)
  • Two pieces 9.5 inches by 5.5 inches for side panels
  • Handle: 9 inches by 3 inches
  • Handle interfacing: 8 inches by 2 inches
  • Strap: 42 inches by 3 inches
  • Strap interfacing: 41 inches by 2 inches
  • Tabs: 2.5 inches by 2 inches
  • Tab interfacing: 1.5 inches by 1 inch

 Prepare the pieces

Ensure all the material dimensions are correct.

To save time, layer the lunch bag body’s vinyl fuse, insulation, lining and exterior fabric pieces on top of each other with all edges aligned. Place the top flap pattern’s curved edge along one short fabric end. Pin the pattern in place and use the pattern as a guide to trim the fabric corners. Alternatively, cut each layer separately. Note that placing pins through the vinyl fuse may cause permanent holes. Place pins within the seam allowance or use clips.

1. With the right sides up, place the body and side panel exterior pieces over the corresponding insulation pieces and pin in place. Baste around the edges using a centimeter wide seam allowance. 

2. Before fusing the vinyl to the lining, trim each piece of vinyl fuse a quarter inch on all sides. Make sure all the lining pieces are ironed perfectly flat. With one lining piece right side up, place one corresponding vinyl fuse piece directly in the center of the lining. Fuse the vinyl to the lining according to the manufacturer’s instruction. Repeat for all three lining pieces.

3. With the exterior body (and attached insulation) fabric right side up, center the loop side of the hook and loop tape 1 inch in from the short straight edge. Edgestitch around the tape. Similarly, with the lining body fabric right side up, center the hook side of the hook and loop tape three-quarter inch in from the curved edge. Edgestitch around the tape.

Create the handle

  1. Place the handle interfacing fusible side in the center of the handle fabric’s wrong side. Fuse in place then, fold both long edges in half an inch and press. Repeat with the short edges. If desired, miter the corners.
  2. Fold the handle piece in half lengthwise and press. Edgestitch along the three open edges.
  3. Repeat steps 1 and 2 for the strap then, fold about half an inch of one strap end around one swivel hook ring. Stitch in place close to the fabric edge. Repeat on the opposite strap side. The tabs are made in almost the same manner. Begin by placing one tab inter facing’s fusible side in the center of one tab fabric’s wrong side and fuse in place. Next, fold both short edges in half an inch and press. Fold the piece in half lengthwise so it measures three-quarter inch wide. Edgestitch along the open edge. Finally, fold the tab in half width-wise around one D ring so the raw edges are even. Place in place and repeat for the second tab.

Sew the lunch bag

  1. Place the body’s exterior and insulation piece right side down. Use a ruler to make three marks at the following points: 9 inches from the short straight edge. 4.5 inches beyond the first mark and 9 inches beyond the second mark. Repeat on the parallel side. Clip into the marks a quarter inch at all six points. This makes it easier to sew the side panels in the following steps.
  2. Pin each tab and D ring unit (from step 3 above) on the exterior body piece’s right side about two centimeters below the mark closest to the top flap. Be sure to align the raw edges. 
  3. With the right sides together, align one exterior side panel piece with the top corner of the exterior body piece and pin along the long edge. Note that the side panel should extend half an inch beyond the first nine-inch clip.
  4. Rotate the side panel so the short edge aligns with the body piece’s long edge and pin. This corner should extend half an inch beyond the second clip. Rotate the side panel one more time and pin the adjacent side to the body piece’s long edge. Here, the side panel’s top edge should end exactly at the last clip.
  5. Using a half-inch wide seam allowance, stitch the side panel to the body piece. Sew down one long edge of the side panel, across the bottom, and up the remaining long edge. Be careful not to sew over the bunched fabric when pivoting at the corners. Finish by trimming the corners and seam allowances only along the side panel edges. Do not trim along the top flap.

Repeat steps 3 through 5 on the second side. Then repeat steps 1, 3, 4, and 5 for the lining pieces. Again, try to pin the lining pieces within the seam allowances or use clips to avoid making permanent holes in the vinyl.

  1. Turn the lining right side out and slip the entire lining unit into the exterior body unit with right sides together and corresponding edges aligned. Pin around the open sides and the top flap, being sure to match all seams. Stitch around the pinned sections using a half-inch wide seam allowance. Leave a three-inch wide opening for turning the lunch bag right side out.
  2. Trim into the corner and seam allowances to reduce bulk. Turn the lunch bag right side out and give the exterior a final press. Hand sew the opening closed or topstitch around the entire top edge. 
  3. Pin one handle side 8.75 inches up from the lunch bag base and a quarter inch in from the side edge. Stitch close to the handle edges through all layers, forming a rectangle. Repeat on the other side. TipIt helps to place clear tape along the sides of the feed dogs to help the vinyl move more smoothly through the sewing machine.
  4. Clip the strap onto the D rings to finish off the lunch bag.

How to sew a lunch bag

This is a simpler design than the one described above

Materials required: 

Insulated interfacing, wipe-able fabric for easy cleaning, lining fabric, Velcro, and optional mesh.

Cut your fabric

Figure out what size you require then cut the fabric accordingly.

Here we are going to make one of the lengths of 8.5 inches, the width of 6.5 inches and 1.8 inches wide. A piece of material 15 inches by 16 inches will be adequate.

Procedure

  • Place the main fabric right side together and then place the interfacing on the wrong sides of the fabric.
  • Sew down both sides and across the bottom, catching all four layers. Repeat sewing sides and bottom of lining fabric.
  • Fold the main fabric and the lining inside out. Fold the side seam so it lays on top of the bottom seam. Measure 4 inches from the corner and place pins to mark this area.
  • Sew on this line, and then trim off the corner. Repeat with the lining.
  • At this point, test your lunch box to ensure it fits in the bottom of the bag.
  • Place the lining and the main lunch bag right sides together, aligning the top raw edge. Sew around with a seam of about one centimeter. Leave a 4-inch opening to turn the bag.
  • Turn the bag right side out and push the lining inside the lunch bag. Press the top edge of the bag flat and close the turning hole. From the lower corners of the bag, pinch and clip straight up to the top. This will create a fold on each corner of the bag.
  • If you want an outside mesh pocket, now is the time to prepare it. Cut a pocket 8 inches long by 4 inches wide and finish the top edge with fold-over elastic. Clip to the folded corners and leave the bottom open for now.
  • Sew down the four corners with a quarter inch seam allowance. Try to catch the outer fabric, the insulated interfacing, and the lining all in the stitching. 
  • After you have sewn the corners, place a ribbon on the bottom of the pocket and stitch to close the pocket.
  • Cut 1.5-inch pieces of Velcro and place the corresponding pieces in each corner and sew.
  • Add 2-inch pieces of Velcro to the opening. The top should now close completely with the Velcro. If you want the top to be more secure, add long pieces of Velcro to both side folds. Now you have your lunch bag ready.

Factors to consider when purchasing a lunch bag.

1. Insulation

A good quality lunch bag will always have insulation. This is to allow your food to stay cool throughout the day.

2. Bento box style

These types of lunch boxes are a growing trend and are ideal for those who like to carry a range of items in smaller portions and want a convenient way to carry them all without spilling. The only challenge with them is that they are a bit challenging to clean.

3. Built-in or included containers

You should consider whether you want any built-in containers in your lunch box. Some will have one or two containers built-in while bento boxes will be completely divided into containers.

A more flexible option is a lunch box that comes with removable containers. This way you avoid the hustle of finding separate containers that fit in your lunch box. Some boxes will even include a water bottle so that you can carry along your favorite drink.

4. Size of bag

You should consider a bag that is large enough to fit your food, a drink along with an ice pack. At the same time, this bag should not be too large to the extent that it occupies unnecessary space. If you are unsure about what size of bag you require, keep in mind that it is better to err on the side of too large as opposed to too small.

5. Color

This factor comes down to personal preference. You can find a lunch bag in nearly any shade or pattern you desire. This means you can decide to keep it professional with a neutral-colored lunch bag or show off your personality with a brightly colored one.

6. Stain resistance

If possible select a bag that resists stains. No matter how well you pack your food, something will eventually leak or spill and can lead to an unsightly stain that is difficult to remove. Therefore, if your bag is stain resistant it will be an advantage to you.

7. Ease of cleaning

This factor is very important when selecting lunch bags for women. Be keen and check whether the included containers or thermoses are dishwasher safe. Also, check whether the lunch bag is machine washable and if the fabric requires any special care.

8. Durability

A good quality lunch box should be durable enough to last a long time. If the manufacturer of the lunch bag offers a warranty then there is a good chance that the lunch bag is durable. Another way you can ascertain the product’s durability is by reading the reviews from people who have already bought the product.

How to keep food cold in a lunch bag

Foodborne illnesses multiply rapidly at room temperature thus your food must be kept cold inside your lunch bag. You will want to use at least 2 cold sources in an insulated bag to keep perishable foods safe; ice or gel packs in your insulated bag work best. You can opt to buy re-usable cold sources or make your own by filling a bottle with water and freezing it.

Tip: Freeze a water-soaked sponge and place it in a Ziploc bag to create a no-mess ice pack. No more leaks!
