FAQ

1. What's the difference between 8011 and 8079 alloys for lids?
8011 is the 'go-to' alloy that has a nice balance of formability, strength, and cost so works well in most cases for food and dairy lid applications. If you have a more complex requirement for integrity of your barrier, great formability, and extended shelf life, then 8079 is the better choice as it has better tensile strength and has better resistance to pinholes.

2. What foil thickness is recommended for lidding?
For lidding, typical foil thickness range is 20 to 40 microns, but if you are looking at lidding small diameter cups or standard dairy products, then 20-25 microns is acceptable. If you are working with large diameter containers, long shelf life products, or if the product is being filled into containers at high speed, then lidding with foil thickness of 30-40 microns is recommended.

3. Can you supply pre-coated lidding foil for lids that are made of different materials (e.g. foam cups or PET cups)?
Yes, we provide heat seal coatings on our lidding foil to be used with a variety of different materials including PS, PP, PET, and PLA. Our Engineering Team can study your sealing process and provide a recommended coating for the material and your sealing process.

4. Will the foil be suitable for both hermetic sealing and easy open sealing?
 Absolutely, we can engineer lidding foil to provide either hermetic sealing, which offers the best barrier protection for maximum shelf life, or easy open sealing that provides convenience to the consumer for a clean, consistent open without tearing. We will tailor the strength of each seal based upon your requirements.

5. What are your capabilities for printing branded lidding foil?
Our lidding foil can be printed in high-definition rotogravure with up to 8 colours using food-safe inks. Branded graphics, such as your company logo, product information, nutrition information and decorative images can be printed directly onto the foil. This will result in eye-catching, shelf-ready packaging that enhances brand awareness and attracts consumers.HTMM's 8011/8079 Aluminum Foil for Lids is widely used across dairy packaging (e.g., yogurt cups, drinking yogurt bottles), as well as other (food, beverage, dairy, etc.) types of food, to provide a reliable seal and consumer convenience in lidding applications. The use of HTMM foils in dairy packaging provides maximum seal integrity while keeping products (yogurt, sour cream, cottage cheese) fresh and preventing leaking while they are being shipped. The lids are easily opened by consumers without tearing due to their consistently designed peelable characteristics. In addition, HTMM provides customers with an attractive, printable surface that can be customized to represent their product's brand, while the foil lid maintains moisture in pudding and dessert cups.

HTMM's foil lidding for ready-to-eat meal and food service containers prevents temperature fluctuations throughout the supply chain and helps companies provide better service to their customers by meeting their quality standards. HTMM's foil lidding is also critical to businesses that manufacture and package yogurt drinks, juice, and other dairy-based beverages, etc. by providing a reliable seal around the container that will prevent leaking during shipment. Lastly, pharmaceuticals and nutraceuticals rely on HTMM's foil lidding solutions to provide the requisite barrier protection required for the stability of tablets and capsules in blister packs, and single-serve powder containers.

Questions and Answers About Aluminum Foil Yogurt Lids

1. What alloy is best to produce yogurt aluminum foil lids?
The most common alloys for yogurt aluminum foil lids are 8011-O, 8079-O, and 1235-O.
8011-O: It provides good strength and barrier properties.
8079-O: This alloy is known for its high elongation properties, or greater flexibility.
1235-O: Preferred for its high purity and ductility.

2. What thickness should yogurt lid aluminum foil be?
Common thicknesses can range from 25 to 45 microns (µm) depending on the yogurt container, sealing layer, and mechanical strength.
25-30 µm: Use for light weight applications
35-45 µm: Used for yogurt lids.

3. What surface treatments will aluminum foil yogurt lids have?  
Aluminum foil will have any surface treatments before lamination or printing.Primer coat for better ink adhesion.
Lacquer coat for heat sealing
Embossing for decorative texture, or easy tearing 
Polishing or bright finish for gloss

4. What is the function of the heat-seal layer in yogurt lids? 
The heat-sealing layer (typically PET, PP, or PS film) is laminated to the aluminum foil to ensure the aluminum foil can seal tightly with the yogurt cup without leaking. Also, it allows the lid to peel easily without the yogurt cup tearing which creates the users preference of convenience and hygiene.

5. In what ways do aluminum foil lids help in food safety and freshness? 
Aluminum foil has total barrier qualities to light, oxygen, water vapor and odor. It protects against bacterial contamination, oxidation of flavor and loss of flavor - thereby maintaining yogurt freshness longer.

6. What are the standard size widths and cores for jumbo rolls of aluminum foil for yogurt lids? 
Width: 200 mm - 1600 mm (customizable) 
Core ID: 76 mm or 152 mm (paper or aluminum cores)
HTMM can customize the roll gauge based on your slitting machine specifications. 

7. Can aluminum foil yogurt lids be printed or embossed?
Yes. Aluminum foil has a fantastic printable surface to allow multi-color flexographic, rotogravure or digital printing to be applied. Embossed foil lids can also be made in order to create texture, design style and to differentiate your brand. 

8. Can the foil be customized to the cup material (PP, PS, or PET)?
Yes. The sealing lacquer or film would be matched to the yogurt cup plastic type to achieve a successful seal. For example:
For PP cups → aluminum + PP film
For PS cups → aluminum + PS lacquer
For PET cups → aluminum + PET film
